While graph view offers a broader perspective on the test results with a two-dimensional view, the compare view offers a more analytical perspective on 2 specific commits or over an aggregation of values. The revisions to compare against could be chosen from different repos.
Compare View can be used for various situations, a few examples here:
- when we perform a bisection and we want to analyze the difference between two try pushes, baseline vs backout to find out which changeset introduced the regression
- when we create a patch and we want to check if the new changes fixed/improved a regression
Compare view is located in the menu of perfherder app.
Compare view offers a detailed end-to-end analysis over test results, including subtests, deltas, and magnitude of the difference.
Below you can watch a video describing the steps to choose revisions to compare, framework, how to retrigger, etc.
