# Scripted tests
|
|
|
|
Each D file is treated like a shell scripts which executes one or multiple
|
|
complex tests. The test result is indicated by the scripts exit code,
|
|
|
|
```
|
|
0 the test was successful
|
|
dshell.DISABLED the test was skipped based on the environment
|
|
* the test failed
|
|
```
|
|
|
|
## Purpose
|
|
|
|
These scripts are intended to supports tests which cannot be implemented in any
|
|
other test category. For example, [this test](sameenv.d) verifies that the
|
|
process environment is propagated correctly to an executable run by `dmd -run`.
|
|
|
|
This can also be used to aggregate several such test cases into a new category
|
|
(e.g. as done for [DWARF debug info generation](dwarf.d)).
|
|
|
|
## Remarks
|
|
|
|
Scripts should prefer the following wrappers defined in the [`dshell`
|
|
module](../tools/dshell_prebuilt/dshell_prebuilt.d) instead of the plain
|
|
Phobos functions s.t. the test runner can issue a proper log on failure.
|
|
|
|
Note that `dshell` tests require additional code and linking another
|
|
executable, so they should be the last resort if a the test setup
|
|
cannot be represented in any other test category.
|
|
|
|
Refer to [test/README.md](../README.md) for general information and the
|
|
[test guidelines](../README.md#test-coding-practices).
