@jdunkerley, it is possible to run these tests quickly:

sbt:enso> std-tests/clean
sbt:enso> std-tests/test
[info] Test run org.enso.base.polyglot.tests.EnsoMetaTest finished: 1 total, 3.595s
[info] Passed: Total 1, Failed 0, Errors 0, Passed 1

e.g. the test finished in less than four seconds (or in eleven seconds on CI).

  • originally I wanted to add these tests into std-table
  • but there is recursive project dependency
  • as test-utils depend on std-table (to have Enso distribution fully built)
  • and making std-table depend on test-utils was ... complicated...

To debug:

  • but breakpoint on line 23
  • let your IDE listen to port 5005
  • invoke following in the sbt
sbt:enso> project std-tests
sbt:std-tests> withDebug --debugger testOnly -- *EnsoMetaTest
obrazek

assertTrue("Is meta object", errorType.isMetaObject());
var fqn = errorType.getMetaQualifiedName();
assertEquals("Standard.Base.Error.Error", fqn);
var error = errorType.invokeMember("throw", "error message");
assertTrue("An error was created", error.isException());
try {
throw error.throwException();
} catch (PolyglotException ex) {
assertEquals("Converted to panic with the same exception", "error message", ex.getMessage());
}
}
