[SWT-NNNN] Dedicated `.bug()` functions for URLs and IDs

2

One of the features of swift-testing is a test traits system that allows associating metadata with a test suite or test function. One trait in particular, `.bug()`, has the potential...

Split `.bug()` into two taking a URL or a number.

1

This PR changes the initializers for `.bug()` from ones taking an undecorated and unspecified "identifier" to ones taking either a URL (as a string) or a numeric ID ("bug number.")...

Replace `#fileID`, `#filePath`, `#line`, and `#column` with a single macro.

1

We have a bunch of functions that take separate, defaulted arguments for file ID, column, etc. We'd like to normalize these functions to always take a single `SourceLocation` instance, but...

[WIP] Enable support for the `@_section` experimental attribute.

8

This PR enables support for `@_used` and `@_section` to allow embedding test data directly into its own section in a binary. This means we don't have to look up synthesized...

Improve diffing of collections and structured values.

6

This PR improves the test output when comparing collections and structured values (using `#expect()`) when the comparison fails. Previously, we'd just the insertions and deletions as arrays, which was potentially...

Cannot enable C++ interop (deployment target too low)

1

We cannot enable C++ interop in the package because it is only available as of macOS 13 (and aligned Apple releases.) Attempting to build produces this error diagnostic: > 🛑...

`swift test` should warn when `--filter` excludes all tests (_à la_ XCTest.)

1

When using XCTest and `swift test --filter`, if all tests are filtered out a diagnostic of the form: > warning: No matching test cases were run Is emitted by SwiftPM....

Reduce overhead of `.expectationChecked` event handling in `#expect()`.

1

This PR refactors the implementation of `#expect()` and `#require()` a bit such that they don't incur more than minimal overhead posting `.expectationChecked` events if nobody is listening for them (which,...

Clarify that 8-bit exit codes aren't a problem on macOS and Windows.

4

The documentation for the experimental exit tests feature currently says that on POSIX-like systems, only the low 8 bits of a process' exit code are preserved. This would be true...
