[dart-misc] running tests with pub

[Daniel Davidson]

I've been using test package for a while and I run tests on drone by
invoking the scripts directly.
Some of my tests need to write files into the current directory and then
clean them up.

This line:

String root = dirname(dirname(absolute(Platform.script.toFilePath())));

gets the path of the root of the package. This fails when run via pub.
It seems the Platform.script.toFilePath() does not really resolve to a path
when run using pub test, but works fine when running test script with dart.

What is the workaourd?

Thanks

I think this is still work in progress and caused by Dart VM limitations.
I think http://stackoverflow.com/questions/30214563/get-current-script-path-or-current-project-path-using-new-test-runner should provide some more information (didn't check in detail).

Ugh, yeah, this is way harder than it should be for a variety of reasons.
If this is just for tests, you can use mirrors, which is what I do to
address this in dart_style
<https://github.com/dart-lang/dart_style/blob/master/test/formatter_test.dart#L137-L142>
:

// Locate the "test" directory. Use mirrors so that this works with the
test
// package, which loads this suite into an isolate.
var testDir = p.dirname(currentMirrorSystem()
.findLibrary(#dart_style.test.formatter_test)
.uri
.path);

This works if you run the test suite directly in the VM or if you run it
through pub run test. I'm not sure about Drone.

Cheers!

Thanks. I'm ok, I mainly needed to get test working for CI. I was switching
from drone to travis since travis seems to be keeping up with sdk versions.
In the process I thought I'd try out the pub test approach used by kevmoo's
projects.
But, for this case it won't work, so I'll just go back to invoking dart
directly to test.
