Quality Analysis

Software Testing Life Cycle

What is Software Testing?

Software testing is a process of evaluating the functions of software apps for finding any software bugs. It checks for bugs in the developed software met the specified requirements & identifies a defect in the software and make it a quality product.

It implements the following process by verifying & validating a software product:
  • The product is working as per requirement.
  • The same characteristics can be implemented again.
  • It is as per business and technical requirements that guide its design & development.

Why is Testing Important?

Software Testing is important because of the following reason
  • It points out the defects & bugs that were made during the development process.
  • It ensures the product quality while delivering to the customer and gain their confidence.
  • It makes sure that your app requires low maintenance cost & provide consistent, reliable, accurate output.
  • It ensures that your clients find the company reliable & their satisfaction in the app is maintained and it also prevents you from the monetary loss.
Software Testing Life Cycle

Let’s have a look into the detail of the STLC & its different phases of testing

Software Testing Life Cycle

STLC represents a series of activities conducted to perform software testing. Each activity is accomplished in a planned and systematic way & each phase has different goals as discussed below in detail.

STLC

Requirement Analysis

It is the first step of the software testing life cycle that makes quality assurance team understands the requirement like what to be tested.

If something is missing and not understandable then the QA team meets with the stakeholder to gather the detail information of requirements. The testing team starts high level analysis concerning the application under test.

Planning Phase

Generally, Test planning is the initial phase of the testing process. Where you can identify the activities & resources that can help to meet the testing objectives and test team plans the strategy and approach towards the process.

During the planning phase, you can also identify the metrics & method of tracking those metrics.

Planning is done on the basis of requirement, test strategy of the company, & risk analysis.

Test Case Development

It started once the development phase gets started after the completion of test planning & develops the test cases based on scope & criteria’s.

Testing team prepares the required test data for testing & when the test case is prepared they are reviewed by the QA team.

There are several factors which affect the identification of test conditions are as follows
  • Product Complexity
  • Test Management
  • Stakeholder’s availability
  • Levels & depth of testing
  • Product risks
  • Knowledge & skills of the team

Test Environment Setup

It is an important part of STLC that decides the software testing conditions. Environment setup is an independent activity that can be started along with test case development.

When the integrated environment is ready to validate the product test condition can be divided into multiple sub-conditions to increase the coverage.

There are several factors which affect the identification of test conditions are as follows
  • Identify & get the test data
  • Set up the test environment
  • Create the requirement traceability metrics
  • Create test coverage metrics

Test Execution

In this phase testing team start executing test cases bases on real-time validation of product & find bugs.

It ends with exit criteria & reporting. Based on your project & stakeholders' choice where you can decide the reporting schedule on a daily or weekly bases.

There are several reports that you can send and the content of the report changes or depends on the person you’re sending your reports.

A project manager that belongs to the testing background will be more interested in the technical aspect of the project so you have to make a technical report for them. A stakeholder will be interested in the risk analysis reports that have been mitigated through testing.

Test Closure

In the last phase of STLC the process of testing is analyzed & matrix, reports, results are documented.

Wrapping-UP

STLC is a sequence of specific activities conducted for the testing process to achieve the best software quality goals. It provides both validation & verification activities. As we have discussed above that software testing is not only a single testing activity but also consist of a series of activities that help to certify your software products.
