Software Testing & Code Quality

Software Development & Engineering

Software Testing & Code Quality

Software Testing & Code Quality shows how to catch defects early and keep software dependable as it changes. It explains why bugs happen, how to write clear test cases and how unit, integration and end-to-end tests fit together. Higher levels cover test automation in build pipelines, code reviews, quality metrics and testing strategies for large teams.

Levels: 4
Starting from: 210 credits

Choose a level

Each level is unlocked on its own

Level 1 / 4

Beginner

210 credits

What you will study: What defects are and where they come from, the cost of finding bugs late, the testing pyramid, manual and automated testing, and basic quality vocabulary used by teams. Real bug examples make each concept easy to picture.
Who it is for: For developers, analysts and newcomers to quality work who want to understand why software fails and why structured testing matters before any code is released. No testing background is required to follow along.
What you will be able to do: You can explain why testing matters, describe the main types of testing and recognise common defect patterns when reviewing a feature or reading a bug report. It gives you a shared vocabulary with any development team.

Level 2 / 4

Intermediate

410 credits

What you will study: Writing test cases from requirements, boundary and equivalence techniques, exploratory testing, unit testing basics, test data, and writing clear bug reports with steps to reproduce. Worked examples show each technique applied to a realistic feature.
Who it is for: For learners who understand testing concepts and want hands-on skill in designing test cases, running unit tests and reporting problems in a way developers can act on. It turns testing theory into everyday working habits.
What you will be able to do: You can design focused test cases for a feature, write simple unit tests, explore software systematically and report defects clearly enough for others to reproduce and fix. Your reports will save developers time and reduce back-and-forth.

Level 3 / 4

Advanced

710 credits

What you will study: Integration and end-to-end testing, mocks and stubs, test coverage, running tests in CI pipelines, managing flaky tests, static analysis and making code reviews more effective. Each technique is linked to the kinds of risk it is best at catching.
Who it is for: For developers and testers who want quality checks built into daily development, so that every change is verified automatically before it reaches users. It fits teams that already practise continuous integration.
What you will be able to do: You can build an automated test suite that runs on every change, choose the right level of test for each risk and use code reviews and analysis tools to raise quality. Fewer defects will slip through to the people using your software.

Level 4 / 4

Expert

1,010 credits

What you will study: Risk-based test planning, testing complex and distributed systems, performance and security testing, quality metrics that matter, test environment strategy and building a shared quality culture. Case-style scenarios show how these ideas work in large organisations.
Who it is for: For quality leads, senior engineers and managers who shape testing strategy across several teams and must balance delivery speed with long-term reliability. It takes a wide, organisation-level view of quality.
What you will be able to do: You can design a quality strategy for an organisation, decide where testing effort brings the most value and use meaningful metrics to guide improvement across teams. Quality becomes a shared responsibility rather than one team's burden.

Levels are paid for with credits. Access details are emailed to you, typically within 24 hours, and if nothing arrives after 72 hours, please contact us.

About This Learning Material

Software Testing & Code Quality treats quality as part of everyday development rather than a final check. It suits developers who want more confidence in their changes, as well as testers and team leads who shape how quality is measured.

The Beginner level explains what defects are, why they appear and the basic types of testing. Intermediate focuses on writing test cases, running manual and unit tests and reporting issues clearly. Advanced covers automated testing inside development workflows, mocking, test coverage and making code reviews more effective. Expert looks at quality strategy across a whole organisation, including test planning for complex systems, meaningful quality metrics and balancing speed of delivery with long-term maintainability.
