[NCrunchConsoleToolv3.17.0.2]

I am doing som trials with NCrunch console with a rather heavy test solution (14k tests) on TeamCity. But I am wondering why some of the failing tests are "disappearing" from the test results? See below:
TestHistory

When I look at the failed tests from #24, they do not have any records in build #25 and #26 (they were not executed since they were not impacted, I should have "Or is failing" in my filter), but shouldn't they be part of the "Ignored" tests?
SpecificTestHistory

Side note: I noticed the NCrunch cache directory is not generating a unique subfolder layout, I guess this means I should not share the NCrunch cache folder for different build configurations? Does this rule apply to all NCrunch's workspace and snapshot directory settings as well?

Thanks

Where tests are excluded using the 'Tests to execute automatically' filter, the engine won't queue them for execution. Thus they won't have a result reported by the run as they also aren't considered to be 'ignored'. I guess this is probably also related to your other question, since essentially the use of the filter (which is very useful and powerful) results in a situation where you have tests missing from the result set. This then gives the 'TestsNotRun' 'Error' situation. I wonder if it might be better to consider such tests as ignored and not trigger the error at all when it is because of a filter.

But all my tests excluded via filter are treated as "Ignored" (which is why I end up with 14 982 ignored tests). But let's leave this particular issue since I want to rerun failing tests anyhow so the behavior of failed tests vs ignored tests doesn't really matter.

I am trying to understand this behavior, I have the same config at TeamCity one time reporting 9018 tests ignored (2 passed), and a later run 262 tests ignored (13 passed and 1 failed).
If I re-run that later build I get same result (262 ignored).

The "Ignored" status of 9018 tests is due to my engine mode of impacted only as I understand it. But why is this suddenly only 262 at a later build?

i.e. what causes the engine to report them as ignored in run1 (due to exclusion by the engine mode), but not report them at all in run2 (which uses same engine mode) ?

Thanks.

*Edit: (The NCrunch HTML report states Tests passed: 14724, failed: 2, not run 262 for tha latter build)

Sorry, I've been meaning to come back to you on this issue.

We've seen it happen inside our own build system recently too. It looks like defective behaviour. Somehow it's possible for the tool to 'miss' a test during a run.

I'm not sure yet why this is happening. It's proving hard to track down. I'll let you know when we have more information.
