[edk2-devel] [Patch v2 01/11] .pytool: Add CI support for host based unit tests with results

Michael D Kinney michael.d.kinney at intel.com
Fri Feb 7 18:13:44 UTC 2020


https://bugzilla.tianocore.org/show_bug.cgi?id=2505

* Add plugin to build and run host based unit tests
* Add plugin that performs a DSC complete check DSC files
  used to build host based tests
* Update DscCompleteCheck plugin to ignore module INFs with
  a MODULE_TYPE of HOST_APPLICATION and library INFs that
  only support a module type of HOST_APPLICATION.
* Fix issues in XML reports from checkers.

+# Host Unit Test Dsc Complete Check Plugin
+
+This CiBuildPlugin scans all INF files from a package for those related to host
+based unit tests confirms they are listed in the unit test DSC file for the package.
+The test considers it an error if any INF meeting the requirements does not appear
+in the `Components` section of the unit test DSC. This is critical because
+much of the CI infrastructure assumes that  modules will be listed in the DSC
+and compiled.
+
+This test will only require INFs in the following cases:
+
+1. When MODULE_TYPE = HOST_APPLICATION
+2. When a Library instance supports the HOST_APPLICATION environment
+
+## Configuration
+
+The plugin has a few configuration options to support the UEFI codebase.
+
+``` yaml
+"HostUnitTestDscCompleteCheck": {
+    "DscPath": "", # Path to Host based unit test DSC file
+    "IgnoreInf": []  # Ignore INF if found in filesystem but not dsc
+}
+```
+
+### DscPath
+
+Path to DSC to consider platform dsc
+
+### IgnoreInf
+
+Ignore error if Inf file is not listed in DSC file
