Test Evidence Overview¶
Test Evidence works like a computer’s “black box” recorder. It sits in the background observing and recording the user’s activity.
Like an aircraft black box, Test Evidence retains a user defined amount of history (typically 5 to 10 minutes).
Test Evidence is not a video recorder. It was designed and built by software engineers specifically to capture the information they need to help them analyse errors.
Test Evidence is used in two ways:
When testing, Test Evidence provides the development team with a full history of what actions the user took. This saves the users having to try to remember what they did just before an error occurred.
For compliance evidencing, a Test Evidence recording provides a detailed, date stamped record proving that a specific activity was undertaken.
The Test Recorder app creates a .tra file which is analyzed by the Test Reviewer app.

What is Recorded¶
The Test Recorder app can capture:
All displays on your computer.
A specific display.
A specific application.
Test Reviewer App¶
The Test Evidence Recorder saves its recordings to a file with a .tra (Test Recorder Archive) extension.
The .tra files are opened in the Test Reviewer application for later analysis.
The .tra files may be archived as proof of test execution, attached to issues in an issue tracker or emailed to others.
Some organizations choose to export the .tra contents to a PDF file and archive that.

The Test Reviewer is used to analyze a tra archive.¶
