I personally liked ChatGPT’s answer also:

While coding and programming skills are not strictly necessary for all testers, having a certain level of technical expertise can be beneficial in many testing scenarios. The specific technical skills and knowledge required for testers can vary depending on the nature of the software being tested, the testing methodologies employed, and the organization’s requirements. Here are a few points to consider:

  1. Testers who possess coding skills can contribute more effectively in certain areas such as test automation, where writing code/scripts to automate test cases can significantly enhance productivity and efficiency.
  2. Testers with programming knowledge can better understand the underlying codebase, identify potential issues, and collaborate more effectively with developers in troubleshooting and providing valuable feedback.
  3. Familiarity with programming concepts enables testers to create complex test scenarios, simulate specific conditions, and perform specialized testing, such as security testing, performance testing, or API testing.
  4. Understanding programming languages and frameworks allows testers to interpret error messages, investigate logs, and diagnose issues more accurately, which can expedite bug reporting and resolution.
  5. Knowledge of scripting languages can help testers in tasks like data generation, test data setup, and test environment configuration.
  6. Testers who can read and interpret code can proactively identify potential areas of risk or vulnerability, ensuring thorough test coverage and reducing the likelihood of critical defects slipping through.

However, it’s important to note that not all testing roles require deep programming expertise. Testers can excel with a combination of domain knowledge, critical thinking, analytical skills, and a solid understanding of testing principles and methodologies. The level of technical expertise required will depend on the specific job requirements, the complexity of the software being tested, and the organization’s expectations.

Ultimately, organizations should assess their testing needs, project requirements, and team composition to determine the appropriate level of technical expertise for their testers. Providing training and opportunities for testers to acquire relevant technical skills can be beneficial in improving their effectiveness and expanding their contribution to the software development lifecycle.

For my own opinion: I actually prefer to hire non-technical people who are willing to learn how to code. They often know how to test and then can put their way of thinking into test automation. Compared to people who start in test automation directly and only want to code, they often fail all creativity and testing technique tests (in interviews).

But I do agree a bit of technical knowledge can’t hurt. I’m not saying they need to dive into code 24/7. But the basic concepts is nice, also a bit of knowledge of CI/CD and how to setup a pipeline through scripting etc.
