This folder contains two types of tests for validating sourcemaps: the debugging behavior and the stacktrace behavior.
Running the tests requires the compilation of the correct targets. DDC currently also requires ddc_sdk.dill
inside {sdkroot}/{out,xcodebuild}/{ReleaseX64,ReleaseARM64}/ddc_sdk.dill
.
Except for that, running them should simply be a matter of executing the *_suite.dart
files.
All tests are plain Dart files and goes in “testfiles” (debugging tests) or “stacktrace_testfiles” (stacktrace tests). They are automatically picked up by the testing framework.
See README.md
in pkg/sourcemap_testing
.
One can filter which tests are run by running (from the sourcemap folder):
dart sourcemaps_ddk_suite.dart -- sourcemaps_ddk/printing_class_fields
One can additionally get debug output for failing tests (i.e. tests with different outcome than expected), e.g.:
dart sourcemaps_ddk_suite.dart -Ddebug=true -- sourcemaps_ddk/printing_class_fields
The latter is also useful in combination with /*fail*/
when adding new tests to see all the places where the debugger stopped (both in JS positions and translated to dart positions).
For instance -Ddebug=true -- sourcemaps_ddk/next_through_catch_test
with a /*fail*/
currently gives output like the following:
Stop #1 test.main = function() { | main() { try { | try { let value = /*STOP*/"world"; | var value = /*STOP*/"world"; dart.throw(dart.str`Hello, ${value}`); | // Comment } catch (e) { | throw "Hello, $value"; Stop #2 try { | var value = "world"; let value = "world"; | // Comment /*STOP*/dart.throw(dart.str`Hello, ${value}`); | /*STOP*/throw "Hello, $value"; } catch (e) { | } let st = dart.stackTrace(e); | // Comment Stop #3 dart.throw(dart.str`Hello, ${value}`); | } } catch (e) { | // Comment let st = /*STOP*/dart.stackTrace(e); | catch (e, /*STOP*/st) { { | print(e); core.print(e); | print(st); [...]
