By understanding the strengths and weaknesses of both manual and automated testing, QA teams can create a balanced testing strategy that maximises efficiency, effectiveness, and product quality.

- Functional testing (unit, integration, system, acceptance)

Functional testing is a crucial aspect of QA, ensuring that a product or system performs as expected. There are four main types of functional testing:

1. Unit Testing:

- Focus: Individual components or units of code

- Objective: Ensure each unit functions correctly

- Scope: Small, isolated pieces of code

- Typically done by developers

2. Integration Testing:

- Focus: How units work together

- Objective: Ensure components integrate seamlessly

- Scope: Larger than unit testing, smaller than system testing

- Done by QA teams or developers

3. System Testing:

- Focus: Entire system or product

- Objective: Ensure the system meets requirements

- Scope: Comprehensive, end-to-end testing

- Typically done by QA teams

4. Acceptance Testing:

- Focus: User acceptance and validation

- Objective: Ensure the system meets user expectations

- Scope: Real-world scenarios and user stories

- Involves end-users, customers, or stakeholders

These testing types ensure that a product or system functions correctly, from individual units to the entire system, and finally, meets user expectations.

Best practices:

- Start with unit testing and progress to integration, system, and acceptance testing

- Use a combination of manual and automated testing

- Involve developers, QA teams, and end-users in the testing process

- Test early and often to catch defects early

Regression testing

Regression testing is a type of software testing that ensures changes made to a system or application have not introduced new bugs or affected existing functionality. It involves re-executing a subset of previously run tests to ensure the changes have not regressed the system.

Objective:

• Ensure changes, fixes, or enhancements have not introduced new defects

• Verify previously fixed defects have not reappeared

• Confirm the system still meets requirements and works as expected

Types of Regression Testing:

1. Full Regression: Re-executing the entire test suite

2. Partial Regression: Re-executing a subset of tests related to the changes made

3. Regression Testing Automation: Using automation tools to run regression tests

When to Perform Regression Testing:

• After changes, fixes, or enhancements are made to the system

• After a new build or release is created

• Before deploying changes to production

• As part of continuous integration and continuous deployment (CI/CD) pipelines
  

Best Practices:

• Identify and prioritise critical test cases

• Use automation tools where possible

• Test in a controlled environment

- Test-Driven Development (TDD)

Excellent choice! Test-Driven Development (TDD) is a software development process that relies on the repetitive cycle of writing automated tests before writing the actual code. Here's a breakdown:

TDD Cycle:

1. Write a test: You write a test that covers a specific piece of functionality in your code. This test should be independent of the implementation details.

2. Run the test and see it fail: Since you haven't written the code yet, the test will fail.

3. Write the code: You write the minimal amount of code necessary to pass the test.

4. Run the test and see it pass: Now that you've written the code, the test should pass.

5. Refactor the code: You improve the code, making it more maintainable, efficient, and easy to understand, without changing its external behaviour.

6. Repeat the cycle: You go back to step 1 and write another test, and so on.

Benefits of TDD:

- Improved quality: Writing tests before code ensures that your code is testable and meets the required functionality.

- Faster development: TDD helps you avoid debugging and refactoring later in the development process.

- Confidence: With a robust set of automated tests, you can confidently make changes to your code without fearing unintended consequences.

- Less bugs: TDD helps catch bugs early in the development process, reducing the overall number of bugs.

Best practices:

- Keep tests simple and focused: Each test should have a single, clear purpose.

- Use descriptive names: Use meaningful names for tests and test data.

- Avoid duplication: Don't duplicate test logic or code.

- Keep the test suite fast: Optimise tests to run quickly, so you can run them frequently.

By following the TDD cycle and best practices, you can write high-quality code that's reliable, stable, and easy to maintain.

- Behavior-Driven Development (BDD)

Behaviour-Driven Development (BDD) is an extension of Test-Driven Development (TDD) that focuses on the behaviour of the system rather than just its implementation details. It uses natural language descriptions of the desired behaviour to drive the development process.

Key aspects of BDD:

- Behaviour: Focus on the desired behaviour of the system, rather than individual units of code.

- Examples: Use concrete examples to illustrate the expected behaviour.

- Language: Use natural language (e.g., English) to describe the behaviour, making it accessible to non-technical stakeholders.

- Collaboration: Encourages collaboration between developers, testers, and domain experts to ensure a shared understanding of the system's behaviour.

BDD Cycle:

1. Define the behaviour: Describe the desired behaviour in natural language, using examples.

2. Write the scenario: Convert the behaviour description into a test scenario (e.g., using Gherkin syntax).

3. Run the scenario: Execute the test scenario, which will initially fail.

4. Implement the behaviour: Write the code to make the scenario pass.

5. Refactor and repeat: Refactor the code, and repeat the cycle for additional scenarios.

BDD Tools:

- Cucumber: A popular BDD framework that uses Gherkin syntax for test scenarios.

- SpecFlow: A BDD framework for .NET that uses Gherkin syntax.

- JBehave: A BDD framework for Java that uses natural language descriptions.

BDD Benefits:

- Improved communication: Encourages collaboration and shared understanding among team members and stakeholders.

- Better requirements: Ensures that requirements are clear, concise, and testable.

- Faster feedback: Provides early feedback on the system's behaviour, reducing the risk of misunderstandings.

- More reliable tests: Tests are based on the expected behavior, making them more reliable and maintainable.

By using BDD, you can ensure that your system behaves as expected, and that the development process is driven by the desired behavior, rather than just implementation details.
