Answer 1

Answer proposal for special Angular/IE case: The only thing that worked so far for me using "karma-ie-launcher", in order to run IE as browser, was modifying "include" property of tsconfig.spec.json to explicitly reference target test file using universal qualified path and not globs e.g. "C:\filepath\my-test.spec.ts", for compilation purposes. "In addition" the test.ts file should be appropriately amended to target said file for test file limitation purposes. Be aware that the cache will need to be initially deleted in IE for this scheme to take effect.

(For Angular/Chrome case modification of test.ts alone would be sufficient.)
