Single assertions are why more helpful over multiple assertions if one of them fails. A clue for the failure reason may be in later assertions and there may not be an optimal ordering. Packing everything in a single There's obviously a limit depending on the kind of assertion. But this is not one of those in my opinion. |

Interesting that we call There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others. Learn more. Only if it is different line/column numbers. In theory we could even pass the those as arguments in case it's useful info. It might be nice for the implementation to batch multiple line/columns into one eval too. Right now it's one eval per location - not one per file. |

If we agree that the pattern in this test is better, I'll rewrite the other tests and then it may be better to move this into a variable. Though we usually prefer having explicit message in tests so maybe not. |

expect
in React lifecycles has a couple of problems:As far as I can tell, this "persist this intermediate value and then assert after render" is widely used so this isn't a new precedence.
