Question

Some people argue that developers should not be involved in testing their own code but all testing should be the responsibility of a separate team. Give arguments for and against testing by the developers themselves.

Answer 1

Developers testing their own code can benefit from their familiarity with the codebase, efficiency in bug identification and fixing, and continuous integration. However, there are concerns about bias, expertise, and potential conflicts of interest.

Step-by-step explanation:

Arguments for testing by developers:

Knowledge and familiarity: Developers have intimate knowledge of the codebase, allowing them to better identify potential bugs and design flaws.

Efficiency: Developers can find and fix issues more quickly, reducing the time and effort required by a separate testing team.

Continuous integration: Developers can continually test their code as part of a CI/CD (continuous integration/continuous deployment) pipeline, ensuring that bugs are caught early in the development process.

Arguments against testing by developers:

Bias: Developers may unintentionally overlook certain types of bugs or be less critical of their own work.

Expertise: Testing requires specific skills and knowledge that may not be possessed by all developers.

Conflict of interest: Developers may prioritize meeting deadlines over thorough testing, compromising the quality of the software.

Answer 2

People code in their own styles which can make it hard for other people to understand it, especially if it doesn't have any documentation, but that could be a reason to let a separate team test it, so the developer can learn how to code in a way that is understood by most people.
