Test Strategy vs Test Plan

Test Strategy and Test Plan are important documents that are used to guide the Testing Process. It contains different specifications and levels, which we are discussing here in a detailed manner.

What is Test Strategy?

Test strategy is a plan for defining an approach to the Software Testing Life Cycle (STLC). In addition, the test strategy provides the following details, which are required while writing the test document:

• What technique must be used in addition to this?
• Which of the modules will be examined?
• What criteria apply for entry and exit?
• What kind of testing is necessary?

Types of Test Strategies

The following are the different types of test strategies:

1. Analytical strategy: For instance, risk-based testing and requirements-based testing are two types of testing. After examining the test premise, such as risks or requirements, the testing team sets the testing circumstances to be covered.
2. Model-based strategy: The testing team selects an actual or anticipated circumstance and constructs a model for it, taking into account inputs, outputs, processes, and possible behavior.
3. Methodical strategy: In this case, test teams adhere to a quality standard (such as ISO25000), checklists, or just a set of test circumstances. Specific types of testing (such as security) and application domains may have standard checklists.
4. Standards or process-compliant strategy: This method is well-exemplified by medical systems that adhere to US Food and Drug Administration (FDA) guidelines. The testers follow the methods or recommendations established by the standards committee or a panel of enterprise specialists to determine test conditions, identify test cases, and assemble the testing team.
5. Reactive strategy: Only when the real program is released are tests devised and implemented. As a result, testing is based on faults discovered in the real system. Consider the following scenario: you’re conducting exploratory testing.
6. Consultative strategy: In the same way, that user-directed testing uses input from key stakeholders to set the scope of test conditions, this testing technique does as well.
7. Regression-averse strategy: In this case, the testing procedures are aimed at lowering the risk of regression for both functional and non-functional product aspects. Using the web application as an example, if the program needs to be tested for regression issues, the testing team can design test automation for both common and unusual use cases.

What is a Test Plan?

A test plan is a document that consists of all future testing-related activities. It is prepared at the project level and in general, it defines work products to be tested, how they will be tested, and test type distribution among the testers.

Before starting testing there will be a test manager who will be preparing a test plan.

Types of Test Plan

There are three main types of test plans, each focusing on different levels and aspects of testing:

1. Master Test Plan: It is a high-level document that outlines the overall testing strategy, scope, and phases for a project. It provides a roadmap for the entire testing process and shows how different levels of testing connect with each other. 

2. Specific Test Plan: It focuses on particular types of testing, like load testing, performance testing, or security testing. It provides detailed instructions and guidelines for carrying out these specialized tests, ensuring that each area is tested thoroughly.

3. Analytical Test Strategies: These are based on specific factors like project requirements, specifications, or risks.

• User Acceptance Testing is based on user requirements to make sure the software meets the needs of the end-users.
• System Testing is based on the technical specifications to check if each part of the system functions correctly.

In summary we know that the Software test Documents plays a important part for making the decision with proper documented way. if you are more interested how the process of Software development happens refer "Software Engineering Tutorial".
