What Is Software Testing Life Cycle (STLC)
Software Testing Life Cycle refers to a testing technique which has unique steps to be accomplished in a precise sequence to make certain that the first-class desires have been met.
In the STLC process, every activity is carried out in a planned and systematic way. Each section has distinct dreams and deliverable. Different agencies have exceptional levels in STLC; However, the premise remains the same.
Below are the stages of STLC:
- Requirements phase
- Planning Phase
- Analysis phase
- Design Phase
- Implementation Phase
- Execution Phase
- Closure Phase
1. Requirement Phase:
During this phase of STLC, analyze and examine the requirements. Have brainstorming classes with different teams and attempt to discover whether the necessities are testable or not. This section helps to become aware of the scope of the testing.
If any feature isn’t always testable, talk it all through this segment in order that the mitigation approach may be planned.
2. Planning Phase:
In realistic scenarios, Test making plans is step one of the testing process. In this segment, we perceive the sports and sources which would help to satisfy the testing objectives.
During making plans we also try to become aware of the metrics, the approach of collecting and tracking the ones metrics.
On what foundation the making plans is done? Only necessities?
The answer is NO. Requirements do form one of the bases however there are 2 different very critical factors which influence test making plans. These are:
– Test method of the organization.
– Risk analysis / Risk Management and mitigation.

3. Analysis Phase:
This STLC segment defines “WHAT” to be tested. We essentially become aware of the test situations thru the necessities document, product risks, and other test bases. The test condition have to be traceable returned to the requirement.
There are various factors which have an effect on the identity of take a look at conditions:
– Levels and depth of testing
– The complexity of the product
– Product and task risks
– Software improvement existence cycle involved.
– Test management
– Skills and expertise of the team.
– Availability of the stakeholders.
We must try to write down the test conditions in an in depth way. For example, for an e-commerce web application, you can have a test condition as “User ought to be able to make a payment”. Or you may element it out via saying “User must be capable of make payment thru NEFT, debit card, and credit card”.
The most critical gain of writing the detailed test condition is that it increases the test coverage considering the fact that the check cases could be written on the premise of the check circumstance, these info will cause to write greater detailed take a look at cases which will eventually growth the insurance.
Also, pick out the go out criteria of the testing, i.E decide some situations while you will forestall the testing.
4.Test Case Designing and Development:
After improvement and planning, it’s time to permit the innovative juices flow! Based on the check plan, testers layout and develop check cases. Next comes the verification and validation of specified requirements within the documentation stage. Also, the reviewing, updating, and approval of automation scripts and check cases are critical techniques of this stage. This section also consists of defining specific check situations with input facts and expected outcomes.
5. Test Environment Setup:
Testing activities want certain environmental factors—along with servers, frameworks, hardware, and software—for executing developed take a look at cases.
Software and hardware configuration, alongside with check data setup, are the main components of this phase. And it’s mandatory to smoke check and to equip your software testers with bug reporting tools.
It’s the task of the QA supervisor supervising the team to attend to putting in the test environment.
Test execution is the system of executing the code and evaluating the anticipated and real effects. When take a look at execution begins, the take a look at analysts start executing the check scripts based totally on check strategy allowed inside the undertaking.
7.Test Cycle Closure:
This is the final phase of the STLC, throughout which a take a look at result document is prepared. This document have to summarize the whole testing technique and provide comparisons between anticipated consequences and real. These comparisons encompass objectives met, time taken, overall costs, take a look at insurance, and any defects found.
- Entry Criteria—take a look at consequences and logging from all preceding levels.
- Exit Criteria—introduced and approved take a look at closure file.
