2. Test Suite
What is a Test Suite?
Test suites or “Validation suites” are a collection of test cases and test scripts, all of which are arranged logically and intend to test the specific functionality or software feature.
ISBTQ defines suite as the set of test procedures or scripts executed in a test run.
Having hundreds/thousands of test cases can be a burden to arrange. Test suites help in categorizing them such that they match analysis or planning needs.
We can also define suite as test case containers since they contain all details and goals of every test case and their system configuration required at testing.
Test suites contain several stages that help define the active, in-progress, or completed testing process’s current status.
What Does Suite Means? Explained by Example
We saw those test suites are containers for test cases used for categorization from the above suites definition.
To better understand what does suite means, let us consider an example of buying groceries online.
- Step 1: Log in to grocery site
- Step 2: Select the address to see region-specific products
- Step 3: Add products to the cart
- Step 4: Make payment and Checkout
- Step 5: Logout
Now suppose the above steps are test cases 1-5. When a tester tests these cases, there will be no point in testing for later test cases if previous ones are not satisfied.
For instance, if the user cannot see groceries according to the location, there will be no point in adding products.
Similarly, if the user cannot add products to the cart, there will be no point in checking out.
So, using test suites, the tester can order the test cases into sequences and achieve better testing results.
Types of Test Suites
Test suites classification into two types according to their functionalities are:
1. Abstract Test Suites
The collection of abstract test cases from a high-level model of the system under test (SUT) is called abstract test suites.
These test suites cannot be used directly on the software as they remain at high-level and lack the software and environment-related concrete details.
2. Executable Test Suites
The executable test suites, derived from abstract test cases, provide low-level execution related information required by the test suite program.
It contains a test harness that acts as an interface between the executable suite and Software Under Test (SUT), thus working on a detailed level and communicating with the SUT.
Features of Test Suites
The test suites definition has sufficiently highlighted that test suites are advantageous to both the testers and their organization due to their test case categorizing application.
However, some other essential features and characteristics are worth mentioning:
- Test Suites test parameters like application, version, environment, and more.
- They provide a means for rapid testing and reviewing of the Software Under Test (SUT) and thus increase productivity.
- After creating the test plan, the next step is to define the suite.
- Test suites definition includes the number of tests and related test cases.
- Automation tools like jUnit, Selenium, and more are useful with test suites.
- The goals and the objectives for test cases are present in test suites.
- Functional and non-functional tests are also part of the test suites.
- Creation of test suites based on both test cycle and test scope is possible.
Test Suites Templates
Test suites carry immense importance in the Software Development Life Cycle (SDLC). Thus, testers must follow specific standards to define suite and various aspects covered in test suites definition.
Test Suites can be pre-defined or created by the testing team as per the project’s requirement.
A sample test suite template is:
Test Suite Summary
The initial section must contain a detailed summary of the test suite. It can include categories of test suites as well to improve the comprehensiveness provided by the test suites.
Test Suite Design
The design section contains details about test suites design and suggestions for enhancing the testing coverage and quality.
After the test suite summary and design aspects are clearly defined, the testing team goes for a formal review.
In this review, the industry standards and regulations are checked and confirmed with the test suites definition as summarized and designed.
Pre-condition and post-condition
The fulfillment of the various before and after execution requirements for test suites are defined and checked.
Before the test suites execution starts, the team decides its expected results through a test suite’s success or failure.
These results, when compared with the actual results, validate the test suites.
Risk Assessment or Analysis
The risks associated with the test suites are identified and analyzed in this section.
These risks have the potential of impacting the testing process and hindering the team’s expected results.
By executing the test cases and their environments, they validate various Software Under Test (SUT) aspects in this section.
Documents and Reports
All the documents and reports associated and attached to test suites are present in this section.
These documents could be anything from screenshots, execution records, reports to other essential materials.
Difference Between Test Scenario, Test Suite, Test Plan, and Test Case
|#||Test Scenario||Test Suite||Test Plan||Test Case|
|1.||It is performed from an end-user perspective.||It is of two types, namely executable and abstract.||Level, type-specific, and master test plan are its types.||Two types of test cases are present, formal and informal.|
|2.||Test Scenarios derived from the use cases ensure complete test coverage.||Separate test suites make testing hassle-free, flexible, and agile and thus exceptionally advantageous to the team.||The Test Plan derives from the Use Case Document, Product Description, or Software Requirement Specifications (SRS).||Test Cases are derived and designed from test scenarios according to the Software Requirement Specification (SRS).|
|3.||These are conditions in which any software functionality can be tested.||Test suites definition states that it comprises of a collection of test cases and is prepared after test plan creation.||A document defining the objective, scope, and strategy of software testing is called a test plan.||The various crucial details about testing are contained in a test plan.|
|4.||Various operations performed by the testing team on a product are defined in test scenario.||The goals and objectives of test cases that test the software are included in test suites definition.||Test plan includes details about the testing process in a standardized template.||The set conditions that help in verifying the software compliance with specified functionality is defined in test cases.|
Test Suites, though vital for the testing process, are most often overlooked by novices and experienced testers alike. They cannot understand its importance and use it interchangeably with the test plan, test scenario, and test case. However, test suites are a very crucial part of testing, without which the testing process will be impossible to implement smoothly.
