how do you choose automated testing over manual testing

When deciding between automated testing and manual testing, several factors should be considered.

  • Speed and Efficiency: Automated testing is generally faster in execution compared to manual testing, especially for repetitive tasks. This can significantly reduce the overall testing time.
  • Cost-effectiveness: While automated testing may require a higher initial investment, it can be more cost-effective in the long run, especially for projects with frequent testing cycles.
  • Accuracy and Reliability: Automation testing is often more reliable and accurate as it eliminates the potential for human error in repetitive tasks.
  • Scalability: Automated tests are better suited for testing at scale, allowing you to run multiple tests simultaneously across different environments.
  • Complexity of Test Scenarios: Manual testing is better for handling complex scenarios that require human intuition and adaptability. However, for straightforward, repetitive tests, automation is preferable.
  • Exploratory Testing: Manual testing is more suitable for exploratory testing and identifying subtle issues or inconsistencies that automated tests might miss.
  • Time and Resources: Consider the available time and resources for setting up automated tests. If you have a short deadline and limited resources, manual testing might be more practical initially.
  • Test Maintenance: Automated tests require ongoing maintenance as the application evolves. Ensure you have the resources to keep automated tests up-to-date.
  • Frequency of Testing: If you need to run tests frequently or as part of a continuous integration/continuous deployment (CI/CD) pipeline, automated testing is generally the better choice.
  • Type of Application: Some applications or features may be more suitable for automated testing than others. Consider the nature of your application when making this decision.
