[Test Framework] - Tests for report downloads

[demeritcowboy]

Overview

This is similar to the mail_report job tests in api/v3/JobTest, but it's for when you choose to export from the civireport actions dropdown. This tests that it does export the expected content, at least in the requested format since comparing the actual rows in something like a pdf is hard.

Technical Details

I'm 50/50 on the use of runInSeparateProcess for the pdf one, but otherwise it complains about headers already being sent which is coming from dompdf. The same problem doesn't happen with csv because it calls a helper function which just calls the CMS to spool headers, and it doesn't get output until civiExit().

Comments

Is test.
