Test Automation is a practice where application tests are run automatically and continuously throughout the development process. Test-driven development and the use of unit tests are used to create and maintain acceptance tests that are reproducible and executed with each build.

rest automation
  • Define and execute a consistent and repeatable process.
  • Amplify feedback and improve team communication.
  • Improve overall release deployment quality.
  • Accelerate the delivery of application features to production.


Applications require several techniques and levels of testing to meet quality and user expectations. A typical project will implement a strategy similar to that of the Agile Testing Quadrants model shown here.

The stages of Test Automation are shown in the diagram below. These will vary slightly based upon team structure and organization focus.




Key Metrics

Test Code

Test Code Coverage

identifies the percentage of code in which functionality has been verified.

Defects Reported
Defects Reported Post Release

indicates that requirements may not have a common understanding and/or automated testing is incomplete.

Test Execution

Average Test Execution Suite Time

impacts the available time for builds.

Red Flag Areas

  • Lack of Code Coverage Statistics indicates limited testing being done during development.
  • Lack of Quality Test Data indicates poor test data management, which will produce unexpected application results in production.
  • Long-running Test Suite conflicts with the need for fast builds and often results in tests being skipped during builds.
  • Excessive Notifications result in team members ignoring important alerts, particularly for test results that produce false positives for defects.

Key Roles

System Administrator

Responsible for preparing and modeling the test environments and deploying the application into each of them

Test Engineer

Why AEM?

Building quality in…

For the Department of Education’s GENERATE project, AEM executes over 1,500 unit and integration tests with each TeamCity build to enhance the quality of each release.

To provide consistent functionality...

AEM worked with ITHAKA to build a Selenium-based test suite for their JSTOR application. Using this automated test suite, they were able to validate and maintain functionality across multiple browser platforms with each application release.
