}

if the content before the first test are different the test fails and gives

There was 1 failure:

1. CustomBlockFunctionalTest::testBlockContent with data set "block 1" ('fc4970c1-ed11-4ea9-adb9-47f40b37aff9', 'Edit Title-1')
   Title mismatch -2 Edit Title-1 Edit Title-1
   Failed asserting that false is true.

But if I run the test again, it passes
