Also known as “validation suite,” a test suite is a collection of various test cases that are intended to test a software product or its specific functionality/feature, once the software development is accomplished.
Additionally, these can also be termed as a container for test cases, as it incorporates detailed information and goals for every test case, with complete details about the system configuration, which required at the time of testing. The test cases defined by the test suites consists of various stages and offer overview for every test.
Moreover, a test suite also has several stages, which helps define the current status of the testing process, such as active, in-progress, and completed.
Test suites offers various advantages to the team of testers as well as the organization they are working for. Therefore, to offer you a better insight into its qualities, mentioned below are some of its important features:
Test plan is sub-categorized into test suites and these test suites may further be subdivided into number of test cases. This overall study of test suites and test cases provides a better test plan.
Typically, test suites are divided into two types, with distinct functioning. These also describe the importance as well as the usability of test suite in software testing life cycle. Hence, the type of test suites are:
Since the importance of test suite is immense in Software Development Life Cycle (SDLC), it is vital for software testers to follow a standardized template to create test suite and define the various aspects covered by it.
These templates can either be predefined or can be created by the team as per the requirements of their project. Hence, to help you with the process, here is a sample of test suite template.
To help you better understand the significance of test suite, following is an example that aptly reflects its importance during software testing.
An application has some metrics:
Current version: 2.2
Previous version 2.1 has 500 test cases.
For version 2.2, there are 300 test cases to test the new functionality.
Therefore, the current test case has: 500+ 300 = 800 test cases, including regression testing and new functionality.
Thus, Test suites can generate several test cases for each different requirement.
Since the importance of test suite is not known by software testers, they usually use it with other testing components like test case, test plan, test scenario, etc. Therefore, to help you understand its relevance, here is a detailed comparison:
|Test Plan||Test Suite||Test Case||Test Scenarios|
|1. Test plan is a document that defines the scope, objective, and strategy of testing.||1. Prepared after test plan, test suite consists of a collection of test cases.||1. Test case is an important document that consists of various crucial details about testing.||1. Test scenarios or test condition is any functionality of the software that can be tested.|
|2. It is of three types, level specific, type specific, master test plan.||2. It is of two types, abstract and executable test suites.||2. These are of two types, formal test cases and informal test case.||2. It is performed from the perspective of the end users.|
|3. It follows a standardized template, which offers details about the testing process.||3. Test suites define the objective and goal of test cases that are intended to test the software product.||3. It defines a set of conditions that help verify the compliance of the software with specified functionality.||3. It defines the various operations that are performed by the team on the software product.|
|4. It is derived from Product Description, Software Requirement Specifications (SRS), or Use Case Document.||4. Separate test suites offer great advantages to team and it created testing to be hassle free, flexible, agile.||4. These are derived from the test scenarios and are designed on the basis of Software Requirement Specification (SRS).||4. They are derived from the use cases and they ensure complete test coverage.|
Though test suites are an integral part of testing life cycle, they are usually overlooked by novice as well as experienced software testers, as they do not understand its importance and therefore, use it interchangeably with test case, test plan, test scenario, etc. However, test suites are vital for testing and without them, it will be impossible for the team to implement thorough software testing.
