I think it’s the right kind of tests.
You could use assertSame directly on the array instead of each key/value I think.

@come-nc thank you very much for the review.

The reason I didn't use assertSame on the entire array on some tests like $this->assertSame($result, $circleData) is because the structure returned from CircleService methods is slightly different from the one returned by the AdminController methods. So instead, I compared what I judged the more relevant key/values for each scenario.
