To consult an AB test report and details, you should go to the AB test list view (left-side navigation > Campaigns > AB), and select the test you’re interested in by clicking on the report button:
On the report page, you can see your test details and settings. If the test has a winner selected, we can see the winner’s details. If the test's winner had already been sent and its expire date has passed, you will be able to see its results.
After the test end date you can verify the variants’ results (sent, delivered, clicked, CTR, and DSP (delivered divided by sent)). The data is presented in a table and bar chart. If there’s no data collected (ex. if the test has failed at some point), you’ll see an empty table and data.
