This might be an expecty bug, I didn't check yet.

For a test like this:

pureTest("demo") {
  assert(
    List(1, 2, 3).sum == List(
      1 + 2,
      3 + 1
    ).sum
  )
}

You will see:

[E] - demo
[E]   assertion failed (../../dev/pass/kernel/src/test/scala/com/ocado/ospnow/wms/tap/kernel/ConsumerOpsTests.scala:62)
[E]
[E]   List(1, 2, 3).sum == List(
[E]   | |           |   |  |
[E]   | 7           6   |  List(3, 4)
[E]   List(1, 2, 3)     false
[E]
[E]

You can see the 7 that was the result of the RHS, but it's not in the valid position.

This one will have to be opened in https://github.com/eed3si9n/expecty (which we delegate power-assertions to). Fortunately, Anton and myself have stepped up as maintainers there.

Out of curiosity, what versions of weaver and scala are you using ?

What would be the rendering you'd like to see ? Honestly I'm tempted to just make the macro fail on multi-line expressions as all possibilities I can think of will be confusing one way or the other.

Also don't hesitate to try out the latest , we're just waiting for CE3 for an official 0.6.0/0.7.0 release but I don't think we'll be breaking much between now and then.

The project I'm using this in isn't really anything for work and there's no immediate need to upgrade 😅 I was just waiting for scala steward to do the job for me...
