“All Code is guilty until proven innocent”

We can’t deliver the best user experience and can’t imagine the improvement in any software or application without software testing. Here I am sharing the role of software testing in SDLC.

Testing, a major part of the software development life cycle is very essential in terms of building a strong business, and as the quote suggests all the code is not majestic until proved right, which is a 100% correct statement.

It is the foremost duty of a software tester to test the software with proper analysis of each and every component used in the application. So, this creates great importance to deliver a healthy product.

What is the role of software testing in software development life cycle (SDLC)?

It is the whole process of investigating, planning, executing, and preserving the software product. This cycle continues until software goes through all these processes.

Testing is an essential part of this process. So, in this blog, I am going to discuss the Software Testing Life Cycle (STLC), the roles of Software Testing, and why it is important in the Software Development Life Cycle (SDLC).

Before proceeding further let us first look back at the 3 most common myths about Software Testing that are infamous all across-

1. Software Testing is equal to Quality Control:

This is a great myth that software testing is exactly equal to Quality Control. The actual fact is that Quality Control involves activities such as taking reviews and analyzing them.

2. Testing is considered as the easiest task:

This is absolutely not correct as the testing process involves coding as well. The tester has to write his own SQL queries or scripts to test the software or an application. So, testing is always not an easy task.

3. Anyone can be a Software Tester:

It is completely a hoax as testing requires some extra talent and skills to check and analyze the whole software or an application.

Yes, in small projects people can consider them as a tester but to be proficient and to deliver a valued beneficial product, one must be very skillful.

These are the myths that are most commonly spread and everyone thinks Software Testing is not a complete necessity. To deal with all these myths here are some of the important facts that will make you understand the importance of Software Testing and why it is the necessity of the IT and Software industry.

Software testing also follows a cycle that every QA or test team member follows. This cycle is known as Software Test Life Cycle (STLC).

Knowing the Software Testing Life Cycle (STLC):

Software Testing has a major role in the whole SDLC. The foremost understanding requires having deep integrational knowledge to do specific tasks at various stages of the Software Testing Life Cycle (STLC). STLC is a part of SDLC and comes under the Testing part of it.

The role of Software Testing revolves around STLC which has some phases to pass the Software with major bug-free code. Those phrases that Software Testing involves to be a major part of SDLC are as follows:

I. Requirement Analysis:

The study of requirements is done here. The QA team may interact with the client, Business Analyst, Technical Leads, and other major responsible persons to understand the requirements.

II. Test Planning:

Efforts and cost estimations are determined in this process. A proper plan is prepared for any project in this phase. This may be done by a senior QA team member.

III. Test Case Development:

Test cases are prepared in this phase and the scripts are written to analyze the functionality. The functionality is verified and reworked for any test cases. This is done by any QA team member.

IV. Test Environment Setups:

This is the phase of Software Testing where the program is analyzed and decisions are taken for the software and hardware conditions. In this process, QA or test team may not be completely involved but it can be done in parallel to the Test Case Development phase. This is the specific phase of Software Testing in which the test environment is specified under which the Test or QA team analyses the software.

V. Test Execution:

During this phase of Software Testing, the testers will carry out the testing which will be based on the test plans and the test cases. The bugs will be reported to the developers and retesting of the software is done here.

VI. Test Cycle Closure:

This is the essential phase of the Software Testing as the cycle is about to complete. So, the test team will analyze the current scenarios and will plan the future aspects based on the current results that they have delivered. This is basically to remove the testing process bottlenecks for future test cycles.

Now that Software Testing Life Cycle is clear to you, so, let’s dive into the core substantiality of Software Testing and know the major roles that are involved in Software Testing.

What software testing is responsible for- the major roles of it:

1. Understanding the mindset and requirements of the client:

It is the most common and the first thing that the Software Testing process involves. While the product may technically sound good, but there may be the chances that the team may go too deep in technical details ignoring the actual requirements.

So, before really coming to the software test planning, it is the basic role of a Software Testing or QA team to gather the client’s requirements and understand the perspective of the client.

2. It is essential to know the platforms and the Target Devices:

It is essential to know the platform and the devices that the software is going to run on. There are a variety of devices and platforms available in the current technological world. The devices may include desktops, laptops, tablets, and mobile devices where the requirements of the software are meant to be implemented.

So, it an important role involved in Software Testing to get the client’s agreement over the testing platforms and the devices. This will help in shortlisting the targeted devices and the platforms where the audience will gather.

3. Essential to design the strategy – the test scenarios:

While moving forward for the Software Testing after gathering all the information and the requirements, it is one of the major roles that the team of the testers must design their strategies, plans, and the tasks. The team must divide the tasks in the hierarchal order and distribute the work for the test cases as they plan.

This task may be single handedly operated, but in that case, too, the strategy matters a lot. So, it becomes necessary to understand the business needs and opting for the correct testing techniques and the types.

4. Important to choose the correct testing tools:

Software Testing is incomplete without the right selection of the testing tools. There are many useful testing tools such as Selenium, Protractor, Cucumber, Apache JMeter, Appium, and LoadRunner which are available in the market. This becomes very much necessary to use one of the tools to simulate thousands of users from a single machine. These testing tools can help a tester to generate the test data within a matter of seconds.

In Automation Testing, if decided in the testing strategies then tools like Selenium and WAPT will be a great help. For mobile Testing automation, Appium is a great option. So, to opt for a right testing tool the essential role of Software Testing that the testers adopt in their job.

5. Optimizing and Estimating the QA efforts:

Depending on the testing strategies and the testing tools, a Software Testing process can be optimized and efforts can be estimated for any project that is developed for a client. The role of Software Testing here has an important aspect that gives clear estimations of the Testing process.

Optimization of the tasks can be done by writing efficient scripts using any language. There may be some data-related queries written using SQL which help in testing the correct test scenarios in the project.

Estimation reports can be generated based on the resources and the skill sets that are available in the project. Another option to analyze the resources is to create test data for the application.

6. Scheduling the Quality Assurance Activities:

Now that many of the Roles of Software Testing have been discussed, it is time to consider another important role which is – Scheduling the QA Activities. This task requires analyzing the overall relationship between the ongoing testing tasks, the development tasks, and the approvals by the client or the higher team member. Since the testing tools, the resources available, and the correct testing strategies are known by now, so it becomes a major role to allocate the resources on the right tasks based on the code releases at the regular interval.

This might get delayed as the coding and development part may take more effort and time. So, it is the major part of the Software Testing to analyze all these kinds of things and schedule the QA assurance activities accordingly.

7. Execution and re-testing the scenarios:

This is considered to be one of the major parts of the STLC and the role of Software Testing finally reaches its final part where all that was planned and scheduled is executed properly.

This has as much importance as the planning part and becomes more important as a role when there is the need to perform the risk analyses and some other tasks while the test plan was created.

Considering all these roles there are some of the major tasks that Software Testing consists of:
1. Testing or QA Team to read the SRS document very carefully.
2. The team must make sure to have all the necessary resources available to every member.
3. Preparing the status report of the testing tasks.
4. Ensuring the standards are followed that were decided in the planning and as per the company policies.
5. Designing the re-usable test scripts.
6. Ensuring the proper execution of the test scenarios and delivering a less bug-prone project.
