Find out what exactly a test-suite is, with regards to automted testing

Software testing is a crucial part of the software development lifecycle, ensuring that applications meet functional and non-functional requirements before they are released. Below are some frequently asked questions (FAQs) about software testing, along with clear explanations and examples.

What is a test suite in software testing?

A test suite is a collection of test cases that are intended to be executed together. These test cases may be related by functionality, module or purpose. By organizing test cases into suites, you can efficiently manage, run, and report on large groups of tests.

For example, you might have a login test suite containing all tests related to login functionality, including positive and negative scenarios, boundary cases, and performance tests.

What is a test case?

A test case is a set of conditions or steps used to determine whether a software feature works as expected. Each test case typically includes an ID, a description, input data, expected results, and actual results.

Example:

ID: TC-001
Description: Verify login with valid credentials
Input: Username = user1, Password = pass123
Expected Result: User is redirected to the dashboard
Actual Result: (filled in after execution)

What is the difference between verification and validation?

Verification ensures the product is built according to requirements and design specifications (“Are we building the product right?”).

Validation ensures the product meets user needs and expectations (“Are we building the right product?”).

Verification typically involves reviews, inspections, and walkthroughs, while validation involves executing tests against the actual product.

What are functional and non-functional testing?

Functional testing: Focuses on whether the software performs its intended functions. Example types: unit testing, integration testing, system testing, acceptance testing.
Non-functional testing: Focuses on how the software performs under certain conditions. Example types: performance testing, load testing, stress testing, usability testing, security testing.

What is regression testing?

Regression testing is the process of re-running previously executed tests after code changes to ensure that new updates do not break existing functionality. It helps maintain product stability during continuous development and frequent releases.

What is a test plan?

A test plan is a detailed document that outlines the test strategy, objectives, scope, resources, schedule, deliverables, and activities required for testing a software application. It serves as a roadmap for the entire testing process.

Example Test Plan Components

Test objectives
Test scope (in-scope and out-of-scope items)
Test environment
Test deliverables
Test schedule
Roles and responsibilities
Risks and mitigation plans

Example: Writing a Simple Test Case in Java with JUnit

import static org.junit.Assert.assertEquals; import org.junit.Test;
public class CalculatorTest {

csharp
Copy
Edit
@Test
public void testAddition() {
    Calculator calc = new Calculator();
    int result = calc.add(2, 3);
    assertEquals(5, result);
}
}

In this example, we create a unit test for a calculator’s addition method. If the actual result matches the expected result (5), the test passes; otherwise, it fails.
