Tests for successful compilation
Each D file will be compiled and the compilation is expected to succeed. Any diagnostic emitted must match the predefined diagnostic in the test file, otherwise the test will fail.
Purpose
The point of these files is to test that the compiler successfully emits code without unexpected diagnostics or potential crashes.
A further aim is that when the compiler does fail these tests, the test case should be crafted to make debugging the compiler as straightforward as practical.
Remarks
Test in this directory are not linked by default because linking is expensive
and usually not necessary to reproduce an error. A test may specify the LINK
test parameter to enforce the linking.
Refer to test/README.md for general information and the test guidelines.
