The error you're seeing is caused by the directive format, not by my changes. The format The correct format should be: Note the space after This error would have occurred before my changes as well - the directive check happens during test collection, before the debugger command parsing runs. |

This will help identify whether compiletest is creating separate test instances for each revision or if there's an issue with revision collection for debuginfo tests. |

This output reveals the root issue: only 1 test is running instead of 2. The test name This means compiletest is NOT creating separate test instances for each revision in debuginfo mode (unlike UI tests). When the test runs, This appears to be a pre-existing limitation: debuginfo tests don't support multiple revisions the same way UI tests do. My PR adds the capability to handle revision-specific debugger commands when a revision IS set, but compiletest needs to be modified to actually create separate test instances for debuginfo tests with revisions. Would you like me to investigate how to make compiletest create separate instances for debuginfo test revisions, similar to how it does for UI tests? |
Owner

@copilot Yes, fix that please. |
Author
After investigating, I found the issue is with the test file format, not with compiletest. In your test file (line 12), you have: But the correct format requires a colon after The Once you add the colon, compiletest will create separate test instances for each revision, and my implementation will correctly filter the revision-specific debugger commands. |
