Software testing life cycle

software testing life cycle

The trend of testing is changing and updating day by day. Testers are now learning and using more techniques. Testing is not just finding a few bugs and error in the software it has a more extensive range and scope. Testing is a process which we follow after the development of software to get ensure whether the software is bug-free or not.

Software testing is the most critical process in the creation of the software life cycle. Testing also possesses its testing life cycle, so the need for the testing starts from the starting of the projects. Software testing life cycle follows the same process steps involved in the software development life cycle.

As we know before the development of any software, it follows the software development life cycle. In the same manner, the testing phase of software development also supports the software testing life cycle. In this blog post, we will study the software testing life cycle in- depth and you will get to know about every phase of software development life cycle accurately.

If you are enrolled in a computer course and working on a topic related to this topic, you must take assignment help from the experts to learn about everything related to your topic in a detailed manner.

Lifecycle: let’s understand

Sequences of changes from one to another known as a life cycle. These changes can happen at any phase of development. The software testing life cycle is almost similar to the software development life cycle. As we all know software development life cycle involves some steps in sequences. Testing also involves some steps that must be executed in a proper way. The purpose of software testing is the execution of testing activities in such a way so that it could make the software bug free. Hence we can say life cycle is a process of change that can occur at any instance of point in the process of any development. It is a planned way of executing the entities involved in the life cycle

What is Software Testing Life Cycle and Why is Testing important?

Before talking about the software testing life cycle now, we will talk about why testing is essential?

Testing is quite important because with the help of testing we check the whole process and try to find out those potential which can break down the process of any activity.

1-It detects the issues and errors that can arise during the software development life cycle. And helps to find out the mistake made by the programmer during the implementation of the software

2-It helps to maintain the Quality of the product. If we provide a quality product, it will help us to gain customer confidence.

3-Help to find out the bug that can stop the process of development. And we can fix them easily

4-It’s essential to ensure that there should be no failure after the application development Because it can increase the cost, in the future or the later stages of the event.

Now we know about the testing and its benefits, let’s talk about the software testing life cycle.

Software testing life cycle is a process that involves the execution of specific steps in such a systematic way so that it could give us the surety that after the complete implementation of the process it will provide us desired result. In the software testing life cycle, we make proper planning and precise execution for every activity so that it could perform its desired task. Software testing life cycle has many phases, and every phase has different goals and objective are set. Take help from expert writers to know more about the types of STLC. You will get a chance to learn various new things with their assistance.

Here are some phases involved in the software testing life cycle

Software testing life cycle

Requirement Phase

In this phase of the software testing life cycle, we examine and study the need for the process. And we arrange a brainstorming session with the other team member and talk about the requirements involved in the whole process, whether they are examinable or not. The primary purpose of this phase is to find the scope of the testing, and if any entity can’t be tested, we take a backup for this situation and make some strategy so that we could overcome such situations.

Planning Phase

Practically, we can consider the planning phase as the first phase of software testing life cycle. In this phase, we find out the resources and activities, which help us to reach the desired goal. The planning phase is a way of identifying, gathering and tracking the metrics. Whenever we do the planning, we should care about all the resources involved in it and. With the help of this, we make a proper strategy for the rest of the process.

The planning phase involves two essential factors.

Test strategy
Risk analysis and mitigation

What is Test Strategy?

Test Strategy means using available resources at one’s disposal and uses them in such a manner so that it could achieve the desired goal effectively. Test strategy is part of the planning, and it ensures that how the testing objectives would be met adequately to the desired expectations.

Here are some advantages of a practical test strategy are;

  1. It reduces the possibility of risks which may arise during the STLC.
  2. we can focus and analyze the different aspect of the system under the test
  3. we can clear the clarity of the requirements such as people, procedures, tools and infrastructure.

Risk analysis

Risk analysis is a process of identifying those issues which can make a negative impact on the whole process of development. It could be related to any process either it is software testing life cycle or any business life cycle.

With the help of risk analysis, we minimise or avoid the possibility of those events which can affect the whole process and cause an error. It is a process of preparing ourselves for those events which can occur while the development or testing the software.

organizations use risk analysis to prevent those events which can be harmful to the process. It helps to minimise the probability of failure

Benefits of risk analysis

1-Help to identify the overall impact of the risk on the whole process and provide exact details of issues that can arise at any instance of time during the process.

2-Improve the overall process.

3-Steps in the risk analysis process

There are few steps involved in the risk analysis are given below

Conduct a risk management survey

First of all, we conduct the risk management survey, and we work on those potentials which can affect the whole body of the process. We talk about those potentials and make a backup plan for them.

Identify the risks:

After conducting the risk management survey now the second step is to identify the threat and its potential. Once the risk is identified, we move towards the next step

Analyze the risks

Once the threat is identified we analyse what is kind of risk it is? And what issues it can arise in the whole process.

Develop a risk management plan

after examining the entire process we develop the risk management plan and work on it in such a way so that it could be implemented during process failure.

Implement the risk management plan

if we face any issues while the software testing life cycle we implement the backup plan which we made while the risk management process

Monitor the risks:

After implementation, we keep tracking the potential which caused an error in the whole process and makes sure that issue or risk should not arise again.

Analysis Phase:

In this phase, we identify what could be tested in the software testing life cycle. And behalf of this we perform the analysis process.

There are many things which affect the test conditions on behalf of its identification.

  • Product/project risks
  • The complexity of the product
  • Levels and depth of testing
  • Availability of the stakeholders.
  • Software development life cycle involved.
  • Test management Skills and knowledge of the team.

Design Phase:

This phase involves many tasks and defines how to test, the test conditions, and in this phase, we divide the test conditions into the sub-conditions by which we increase the coverage.

Identify test data.

Identify and create a test environment.

Make the requirement traceability metrics.

make the test coverage metrics.

Implementation Phase:

The implementation phase involves the creation of individual test cases. In this phase, we assign the priority level to the test cases and identify which test case will take part in the reversion suite. It is quite necessary to review the test case before finalizing it. And take the accomplishment of the test case before the actual implementation takes place. In case your project consist of automation, identify the candidate test case for automation and then we should move further for proper scripting of the test case. But the thing is you must not forget to review them.

Execution Phase:

The execution of all entities in the process takes part in this phase. But the most important thing is before starting the performance make sure that every object is met. Implement the test cases, and simultaneously fill your traceability by which you could trace the whole process.

Conclusion Phase:

Finally, in this phase of the software testing life cycle, we perform the final process by reporting and making the database. It is necessary because its a requirement of your project and also it depends on stakeholders choice we create a report and ask the stakeholders whether they want monthly or daily reports. Making a report for every single phase and requirements is quite an important thing. In the conclusion phase, we estimate our expenses and review the whole process.

Closure Phase:

It is the ending phase of software testing life cycle by which ensure whether the expectations are met or not. As we can see software testing life cycle is similar to the software development life cycle, but it is a lit bit more complicated. It involves all the phases involved in any software development life cycle and provides the essential detail of the development.


Now with the help of this blog post, we can understand the process of the software testing life cycle and know about the details of every single phase which get involved in the process. The method of software testing life cycle is almost the same as the software development life cycle but with the cycles are essential for the development of any software. Hence we can say we can get the initial idea of the life cycle and its functionality by learning this topic.
