Debugging and Best Practices

Debugging skills and best practices are what separate stable automation frameworks from fragile ones. This section focuses on real-world failure handling in Robot Framework.

Common Robot Framework Errors​

Keyword Not Found​

Caused by:

  • Missing library/resource import
  • Typo in keyword name
  • Wrong keyword scope

Fix:

  • Verify imports
  • Use auto-complete in IDE

Variable Not Found​

Caused by:

  • Incorrect variable name
  • Wrong variable scope
  • Missing variable file

Fix:

  • Check scope
  • Validate variable files

Timeout Errors​

Caused by:

  • Application slowness
  • Missing waits
  • Incorrect locators

Fix:

  • Use explicit waits
  • Avoid Sleep
  • Improve locator strategy

Debugging Techniques​

Use Log Keyword​

Log    Value is ${value}

Increase Log Level​

robot --loglevel DEBUG tests/

Dry Run​

robot --dryrun tests/

Flaky Test Control​

Flaky tests usually occur due to:

  • Timing issues
  • Shared state
  • Parallel execution conflicts

Solutions:

  • Explicit waits
  • Test isolation
  • Controlled parallelism

Framework Best Practices​

  • Keep test cases readable
  • Push logic into keywords
  • Separate UI, API, DB layers
  • Avoid global variables
  • Keep resource files clean

CI/CD Stability Tips​

  • Run smoke tests first
  • Fail fast on critical failures
  • Track flaky tests
  • Monitor execution trends

Common Anti-Patterns ❌​

  • Overusing Continue On Failure
  • Ignoring test failures
  • Hardcoding environment data
  • Large, unreadable test cases

Key Takeaways​

  • Debugging is a core automation skill
  • Good practices prevent flaky tests
  • Clean frameworks scale better
  • Stability builds trust
