What is a Test Plan in Software Testing?

A test plan in software testing is a thorough document that specifies the testing goals, strategy, resources, and processes for a specific project. It acts as a roadmap ensuring clear testing objectives and efficient allocation of resources and schedules. 

A well-written test plan ensures all stakeholders understand the testing objectives, schedules, and effort required. It also guarantees comprehensive testing of functionalities, UI elements, and other critical components, ultimately increasing testing accuracy and reducing the likelihood of problems throughout the application's lifespan. 

Types of Test Plan

There are 3 types of test plans in software testing that you may need to clarify clearly.

Master Test Plan

This sort of test plan contains numerous test methodologies and levels of testing. It delves deeply into the design and management of testing at various test levels, providing a bird's-eye view of the key decisions taken, techniques employed, etc. It also provides a list of tests that must be run, test coverage, the relationship between different test levels, and so on.

Phase Test Plan

A phase test strategy focuses on a single phase of testing. It provides more details on the levels specified in the master testing plan. The phase test plan includes information not found in the master test plan, such as testing dates, benchmarks, activities, templates, and other details.

Specific Test Plan

This type of test plan is intended for certain forms of testing, primarily non-functional testing, such as plans for conducting performance or security tests.  

Key Components of the Test Plan

A well-defined test plan includes the essential elements for effective software testing. Here are some key components you should include: 

Test Plan Objectives

Every test plan starts with a clear purpose. It delves into specific objectives like identifying software defects, ensuring software quality meets user requirements, and measurably achieving these goals. 

The test plan objectives can use the concept of SMART objectives (Specific, Measurable, Achievable, Relevant, and Time-bound) to emphasize the importance of setting focused and achievable testing goals.

Test Scope

These are the limits of what will be tested. It involves carefully choosing the specific functionalities and features to be tested, ensuring alignment with project needs.

Test Environment Setup

For thorough and reliable testing, you need to set up a specialized testing environment. This part has different types of testing environments, like development, staging, and production, and how to set up hardware, software, and network configurations to mimic real-world usage scenarios.

Entry and Exit Criteria

To start and end the testing phase correctly, you need clear and measurable criteria. Entry criteria are the conditions that must be met before testing can begin. Conditions for entry can be tools that are needed and ready, application needs to be made, and the test results. For instance, when using a model-based testing technique, the test basis is the entry criterion to use this technique. 

Exit criteria are the goals that must be met for the testing phase to be considered complete. Conditions of exit are no big bugs, the passed tests, and test cases running. Examples of exit criteria can be the test basis, risk, functionality, supported configurations, and the software code that achieved a defined level of coverage or did not.

Test Methodology

It covers application testing types like functional, integration, and system testing. You will pick what type of testing to execute on each feature based on the application requirement. Due to potential variations in testing terminology, you should specify the testing methods you will employ to ensure clear communication and understanding among testers, developers, and managers.

Test Schedule and Resources

Making a realistic test schedule is important for managing everyone’s expectations and ensuring timely project completion. The schedule should consider factors like the project timeline, available testing tools,  test case complexity, and the size of the testing team.

Risk Management Plan

Unexpected issues could arise during testing. This plan helps identify possible risks, severity, and mitigation strategies. You can make sure the testing process goes more smoothly and quickly by effectively finding and managing risks.

Who Needs A Test Plan?

A well-written test plan is important for a successful software development process. It offers significant advantages for the following stakeholders.

• Developers: The test plan provides developers valuable insights into the scope and needs of testing. It helps them guess what tests will be run on their code and know the factors for successful testing. 

• QAs: Those make test cases and run them to find bugs and write down what they find. Planning tests help them come up with testing methods, decide how to use resources and keep track of how the testing process is going overall. 

• Product Managers: They use test plans to make smart choices about when to release products, how to allocate resources, and how the quality of the products is generally. It helps them plan release activities, figure out how the changes will affect customers, and make it easier for the development and testing teams to work together.

• Business Analysts: They will make sure that all of the test cases are in line with the business standards at all stages, remaining focused on delivering value to end-users. They get a clear picture of how test cases fit in with real user needs through test planning.

• Compliance Teams: This team can make sure that the testing methods follow the rules that regulators have already set. 

• Support Teams: They will talk to users about known problems, offer quick fixes, and help users find ways to get around them. Based on the test plans, the support team can figure out how to fix the possible problems or bugs found during testing.

How To Develop A Test Plan in Software Testing?

Here comes the 6-step process of developing a test plan for software testing.

Step 1: Define Scope and Goals

Define the test plan's scope and objectives before starting testing. The scope determines which software features, functions, and components are examined and omitted. The objectives explain the testing's expected outcomes and benefits based on company goals and user needs. You should also identify and manage testing risks, assumptions, and limits.

Step 2: Select A Test Strategy and Approach

This step will set the level of coverage, types of testing, quality requirements, and the roles and duties of the testing team throughout the process. The test strategy also specifies the test case design methods, data requirements, testing tools, and environment.

Step 3: Set Up Test Resources and Timetable

Allocate test resources and schedules to start the testing process. Testing requires a tester team, along with hardware, software, and licenses. The test schedule includes test stages, cycles, deliverables, and events, alongside their deadlines, milestones, and dependencies. These have to be prepared before the test starts.

Step 4: Set Test Criteria and Metrics

This phase helps evaluate testing quality and progress. Entry and exit criteria are test criteria that must be met before, during, and after testing. Defect, coverage, efficiency, and satisfaction metrics are test metrics that specify quantitative and qualitative indications for testing evaluation.

Step 5: Document the Test Plan

In this phase, we implement writing the test plan in a clear, concise, and easy-to-understand format. The test plan should include scope, objectives, strategy, approach, resources, schedule, criteria, and metrics. The stakeholders should confirm templates, formats, and terminology used in a project before finalizing the test strategy.

Step 6: Execute and Update The Test Plan

The test plan should be utilized as a reference and communication tool during the testing process. The test plan should be examined amended, and archived for future reference and improvement.
