In today’s rapidly evolving software world, ensuring code quality and application reliability is paramount. Comprehensive testing plays a critical role in achieving these goals. This article breaks down different types of testing, testing styles, libraries, tools, methods, principles, and some essential terminologies.

1. Testing Types

a. Functional Tests

b. Integration Test

Checks the interactions between components. Works with IO Mocks, Stubs, and Fakes to test the happy path.

c. Smoke Tests (Interface Tests)

These tests work with Docker and third-party integrations. They are done to check the built artifact before pushing it to the repository.

d. Consumer Driven Contract Tests (Pact)

Ensures different services in a system interact correctly.

e. End to End Tests (System Tests)

Standalone tests that simulate against a real environment.

f. User Journey Tests (Acceptance Test)

Focuses on the user’s experience. Works on real environments.

g. Non-Functional Tests

2. Unit Testing Libraries

a. Test Libraries

Examples include JUnit and Hamcrest.

b. Matchers

Enable precise test validations.

c. Test Doubles

Include Stubs, Spies, Mocks, and Fakers. These help simulate various conditions and behaviors during testing.

d. Code Analysis Tools

Tools like Static Analysis, Race Condition Detector, and Code Coverage provide insights into code quality.

3. Test Tools

For different programming languages, various tools help facilitate and streamline the testing process:

5. Understanding Test Doubles

In general, these can be termed as “Test Doubles.” But often, you’ll find people informally referring to all of them as mocks.
