Abstract
The majority of the software industry in the world is made up of small software enterprises. To thrive in a highly competitive industry, these tiny software companies must build high-quality software that will assure a long-term business strategy. This is not the case, however, with the company under investigation in this study. The software testing procedure of a small software company in India is critically examined in this article. This company is troubled with software that is riddled with flaws, leading to customers abandoning the program after it has been acquired and cutting relations with the company. We look at the state of software testing in the industry as a whole and try to provide company with a simple and realistic test procedure that will allow them to create higher-quality software.
Introduction
Our country's PM Shree Narendra Modi had announced a project called Atmanirbhar Bharat, in which our country's PM has supported the SMEs(Small and medium-sized enterprises)startups. As we're all aware that Small IT Industry in India has grown with an exceptionally high growth rate in the post-reform years and contributed a large share to the national GDP. Despite the uncertain global economic scenario, the small IT industry has steadily augmented and accelerated the growth of India. This industry consumes a significant pool of competent Indian human resources, transforming India into a worldwide player. This industry absorbs a large number of Indian-trained professionals, developing India into a global IT leader.
Small software firms with less number of people confront numerous obstacles in their quest to develop high-quality software. The first issue is that they do not feel the same processes and approaches that huge software businesses employ are appropriate to them. Cost, a lack of resources, time, and complexity are all possible reasons for not implementing these strategies. The second issue that small software companies face is that their processes and organizational structures are generally unstructured, resulting in a chaotic environment. This is due to the fact that small businesses must focus on time-to-market in order to survive, and they frequently overlook the more resource-intensive formal processes. The third difficulty is a lack of knowledge and experience. Small software companies can't always afford to hire experience software developers.
Our first goal was to learn more about the testing procedure. We wanted to know how software engineers felt about testing, what they knew about it, and how the company felt about it. As a result, the focus of this article will be on Software Testing in small IT firms in India.
What is s/w testing ??
Software testing is all about the investigation done to provide information regarding the quality of service of product to stakeholders.
Also, it provides an independent view of the software to the business in order to understand and appreciate the risks involved in software implementation.
Software testing depends largely on the testing method implemented at the times of development process.
Although, most of the test effort happens after the need have been described and the process of coding has been completed.
Example:-
You've probably heard of websites that announce results on the day they are announced failing. or e-commerce programmes that fail on the major sales day. All of these instances include the failure to conduct appropriate tests or the misalignment of load estimates with actual usage.
The Major Objectives of Software Testing:
Avoid Defects
Locate flaws and errors
Provide details to Stakeholders
decrease risk
Increase Confidence
Test object validation
Verity Requirements
Evaluation of Work Products
Methodology:
Software testing is a huge area that has expanded into its own subject area, represent a variety of testing approaches. Software testers commonly use two testing approaches: black box testing and white box testing. To keep track of progress, it's crucial to master the most often used software testing terms.
White box
White box testing concentrates on systematically examining an application's software. Developers may use white box testing to quickly resolve incorrect lines of code before moving forward with the development process.
The fundamental purpose of white box testing is to ensure that the application code is of excellent quality. Because the inner structure of the system is known, developers can pinpoint the source of issues. In a correctly built white box test, for example, poorly defined variables or incorrect call operations are rather easy to identify.
A white box tester should be a software engineer who is well in expected performance of the application under test. Even with the best-in-class automation systems in place, it may be a time-consuming and exhausting process.
This Testing will help small companies to assure that the code performs as intended and that there are no surprises later on, resulting in the development of reliable software. Software may also benefit from detailed testing to enhance and improve its security, usability, and design.
Black box
Black box testing does not need programming skills. Human users that browse the application interface are known as software users. The usefulness of the program determines whether it passes or fails the test, not the quality of its code.
Because black box testers do not know how the program works, their worries are similar to those of normal users. This technique of testing relies on trial and error.
Programmers may be unable to foresee the path a black box tester will take, resulting in mistakes. The programmer must then examine the code to determine what caused the failure.
Large code sections with well-defined purpose are well-suited to black box testing. Because it allows low-skilled testers to accomplish meaningful work, it's great for outsourced testing. There is no risk of intellectual property theft because the code is not exposed.
This testing will help small companies to assist in the discovery of functional, usability, and other feature shortcomings. This type of testing provides an overview of a software's performance and output. It boosts software quality while reducing time to market. This type of testing reduces the chances of software faults at the conclusion of the user's experience.
Grey box
Grey box testing is a type of ethical hacking in which the hacker uses restricted information to determine the strengths and weaknesses of a target's security network. This type of "ethical hacking" enables software engineers to build fixes and patches to stop malicious attackers from exploiting these flaws.
Grey box testing combines the benefits of both black and white testing (black being when the system or applications code or configuration is unknown while in white it is known). Matrix testing, regression testing, and pattern testing are some of the most common testing approaches used.
This testing aids local companies in obtaining a technique of obtaining faster findings. In today's world, most businesses seek efficiency and precision.
Types of testing
When we talk about testing, we have to keep in mind that there are many various sorts of tests. Categorization is a natural occurrence that takes place throughout time. The sorts of tests are the results, not the objectives.
In terms of degrees, kinds, and procedures, test types are divided into subcategories. Each sort of testing may stand alone as an article or even a book. However, it is outside the scope of this article. As a result, we'll concentrate on the four types of tests that are most important to software developers:
Unit Testing
Integration Testing
System Testing
Acceptance Testing
Each of the four test kinds has its own definition, as well as varied aims and authoring methodologies. Naturally, different methods may be available for each. When you feel it necessary to write a test, you won't be able to pick what type of test to write unless you know what your goal is: to write correctly.
You will not be able to complete your test authoring task if you do not use the suitable test type. As a result, deciding on the correct sort of test to fulfil your objectives is critical.
Unit tests
Unit tests helps in the early detection and correction of issues. Organizations that implement unit testing into their development process and begin testing as early in the lifecycle as feasible are able to notice and address errors sooner.
Your unit testing team serves as a safety shield for developers. Developers can use a complete set of unit tests as a safety net. They may ensure that their recent code changes haven't broken anything by running the tests periodically. To put it another way, unit tests help in the prevention of anomalies.
Unit tests can help to improve code quality. This item is a central feature of the one before it.
Unit tests serve as a backup plan for developers, allowing them to feel more secure while
making changes to the code. They may modify the code without fear of breaking it, improving the codebase's overall quality.
Unit testing may help to improve application architecture. . As of now, consider that if you can quickly add unit tests to a codebase, it's typically a strong measure of the app's architecture quality. As a result, the desire to produce testable code can serve as a motivator to improve architecture. This is why TDD (test-driven development) may be quite beneficial.
Unit tests may be used to provide documentation. Unit tests demonstrate how to utilize the code being tested.
They also say that just a small percentage of organizations unit-test production software. " This means that only a few organizations are capable of producing high-quality software."
You check out software with running tests, and you don't check back in until all of the tests with your modification have been completed.
Writing tests in a single approach, throughout the experience, is practically pointless. When you have to constantly adjust your tests to account for changes made by others, when your tests may be removed by your colleague because 'they won't deploy,' and so on, they are just extra work with the advantages quickly burnt by the rest of the team.
Tests, in experience, are a major advantage for quality, style, and stability of the Project when the complete team agrees.
In smaller companies, unit testing will be essential. Unit testing is performed on all code before it is deployed to ensure that it meets quality standards. This encourages a stable and high-quality working environment. Unit testing helps developers write better, more efficient code and saves time and money across the product development life cycle.
Integration testing
Integration testing is a method of developing components in which testing begins at the top of the software architecture and continues down. It's a type of unit testing that has been extended. Integration testing examines the behavior of a smaller unit of unit testing.
End-to-end testing is used in the vast majority of testing developmental stages. End-to-end testing is critical. However, throughout the software testing life cycle, Integration Test suites are important.
Whether using a top down or bottom up approach to Integration Testing, testing
begins at the very beginning of the development process, catching errors earlier rather than later in the cycle.
The development cycle has a high level of confidence. It’s simple to combine with daily builds and test in a development environment.
Creating the correct test allows for a precise feedback loop between developers and testers. When compared to end-to-end tests, tests run faster.
The percentage of code that is covered is higher and easier to track.
The majority of unit test cases, negative cases, and easier cases can be created earlier in the process and run on every build. It also assists in greater test coverage and reduces test gaps.
A credit card business may add a page where a consumer may request a credit increase, which is coded separately from the login function. Integration tests may be run to ensure that the system remembers the user when they visit to the credit increase page and after a successful request.
Smaller companies will benefit from integration testing since it allows for better module integration, prevents data changes during module transfers,allows for effective
third-party testing and eliminates manual testing issues.
System testing
System testing examines the behavior of an entire and perfectly integrated software product using the software requirements specification (SRS) document as a guide. This testing is primarily concerned with evaluating business, functional, and end-user requirements.
This is a sort of black box testing in which the software's exterior functionality is evaluated using requirement papers and is entirely based on the user's perspective. Internal design, structure, or coding understanding are not necessary for this form of testing.
Only when System Integration Testing has been completed and both Functional and Non-Functional requirements have been confirmed, should this testing be performed.
The focus of integration testing is on detecting faults and problems in system modules.
System evaluation Is a systematical evaluation. When unit and integration tests are used to test sections of a system, this one is used to test the entire system. QA testers are in charge of this testing. For instance, ensuring that emails are sent when testing a whole application from login through checkout. This should not be handled with data mocks or false queries because it is done from the user's perspective. This is the most time-consuming and complicated sort of testing. If an issue is identified during E2E testing, it suggests that unit or integration testing was not completed.
System testing is essential in smaller companies since it uncovers errors and issues before the program is delivered to the client, ensuring that the product is of high quality. It improves the software's dependability and ease of use. Software that has been thoroughly tested guarantees that it is both dependable and high-performing.
Acceptance testing
Acceptance testing is the process of performing high-level, end-to-end tests on a system to confirm that it meets its specifications. Standards specify how an application responds to user actions or events, and acceptance tests are developed from them.Acceptance tests help to focus on the end goal: delivering software that meets a business demand. They bridge the gap between developers and end users, ensuring that the software works in the real world.
Acceptance tests differ from other types of tests in several ways. Because they are mostly responsible for performance objectives. Unit tests for technology question, "Is this function returning the proper value?" "Are the application components interacting well?" asks integration testing. When all is said and done, acceptance tests focus on what matters most: "is my application offering valuable functionality to end users?"
It is impossible to overestimate the significance of these issues. You won't be in business for long if your clients don't get what they came for, either because you didn't accomplish the goals or because you overengineered the solution.
There are two types of acceptance tests:
Application behavior is the subject of functional acceptability tests. "Does the application perform as expected by users?" they inquire.
Security, capacity, and performance are all covered by non-functional acceptance testing. "Is my system secure and quick enough?" there are questions like this.
Acceptance testing is an important part of modern product development for small companies. It assists businesses in determining if a product is ready for real-world use and whether new features are really integrated with current features.
Risks in Software Testing in Small IT Firms:
As firms adopt development approaches such as DevOps or Continuous Integration and Delivery, testing in production is becoming more crucial. Before jumping ahead first into production testing, like with any new approach, it's critical to think about the risks, benefits, and
methodologies. Testing in Production: Risks, Benefits, and Best Practices A software testing firm.
The application and what you're testing impact how you test in production. Regardless of the testing environment, a number of things must be in order to reduce the risks. It's possible that businesses would lose transactions or that test data will be mixed in with production data. The most significant danger of testing in production is the financial risk.
A bad user experience, security flaws, or system breakdowns can all lead to financial losses or reputational harm.
Other dangers include exposing vulnerabilities in project operations, losing data, and depending on end users for defect feedback. In such instance, most users would just abandon the programme with a negative impression of the product, rather than completing and sending an error report. When it comes to new procedures, there is always a good and incorrect way to approach them. Trying to transfer what you've done in pre-production or staging to a live production environment could be problematic. Production testing may go wrong in a variety of ways, and if you can predict at least half of them, you'll be better prepared.
Benefits of Testing in Small IT Firms:
In a fair scenario, all developers would expect that by the time their software solution reaches production, all defects would have been resolved, and no more testing would be necessary. However, in the real world, every sensible and experienced developer knows this isn't possible. There is only one way to discover all of the faults in the production code: test it in production. Of course, testing your product throughout its early phases of development is important, but it isn't always enough. Testing in production allows you to conduct a thorough product evaluation in a real-world environment, and it is the only way to ensure that the system works as planned. With production testing may receive a variety of advantages.
RELEASES IN BETA MODE: Developers may gain early feedback on newly released features by including production testing into your solution's product beta release. Beta versions also give users quick input on concerns with the user experience.
QUICK DETECTION AND LIVE MONITORING: It's a good idea to track app performance in real time as real users change data and interact with the app. In this approach, developers may assess app performance while having full access to all data. Some developers are cautious to implement testing in production because they feel it would interrupt real-world app users' experiences and put data security and stability at risk. It does, however, allow developers to discover and fix vulnerabilities quicker than consumers can report them.
PREDICT THE IMPOSSIBLE: No matter how hard you try, you won't be able to test every single user interaction scenario before the product is deployed. By testing in production, developers can keep track of how well their apps function in real-world circumstances. Production is the only place where developers can track and fix issues that happen through unexpected app interactions.
Production is the only place where developers can track and fix issues that happen through unexpected app interactions.
PERMANENT FEEDBACK: Developers may analyse actual production traffic and user data to see how the user experience changes and how users react to it. By testing in production, developers may accelerate the testing and code integration processes, allowing them to polish the app more quickly and efficiently.
