  • Reduction in Coding for Automated Testing

Earlier, QAs need to create multiple test scripts to test an application, which has slightly reduced to writing a few scripts only. But in 2021, we will see more codeless automated testing than ever before. There are many automation tools built on AI and visual modeling technology, which require no coding at all. Using these tools, QAs can quickly build test scripts without any coding knowledge.

Codeless automated testing is going to be one of the top trends in automation testing in 2021. It is beneficial for testers in multiple ways, such as:

  • Codeless tests are created without any code, making it easier for testers to read and review them quickly without any coding knowledge. It means even non-technical users can review the test cases effortlessly.
  • It doesn’t require QAs to learn new programming languages, which helps a company save its resources, costs, and time.
  • Creating codeless test cases is pretty simple as it doesn’t require any coding knowledge or experience, which saves time for the QAs.

Codeless Test Automation Tools
