How to run Legacy LISAv2 tests
LISAv2 brings incredible value to Linux quality on Microsoft virtualization platforms. To increase the value of LISA, we decide to continue to invest and have more innovation on LISA. So, we started the next version.
During the transition time, we keep validating Linux kernels and distributions. We cannot and don’t want to stop to wait for the exciting current LISA. The two versions will be co-existing for a while. So, the current LISA version supports to invoke previous LISAv2.
With this document, you will know how to run LISAv2 tests in the current LISA. The current LISA clones the LISAv2 repo, start LISAv2, and parse LISAv2 log to generate test results with new format.
🚧 WIP 🚧 Currently we are migrating previous LISAv2 test cases to this LISA framework. Before we complete the test case migration, only T0 test cases can be launched on LISA. Other test cases can be executed in LISA with “Compatibility mode”, which will invoke a shim layer to call LISAv2; so you need to run LISA on a Windows computer and provide the secret file.
LISAv2 should run in the latest Windows 10 client 64 bits, or Windows Server 2019 editions.
Follow LISAv2 document to understand prerequisites and prepare secret files.
Note, you don’t need to clone the LISAv2 yourself, the current LISA will clone it when running.
The Test in Parallel of LISAv2 doesn’t support with the current LISA together. The current LISA implements test matrix to replace current test in parallel in LISAv2. There is no plan for compatibility with LISAv2 on this.
The LISAv2 results is possible to be missed in a rare race condition. There may be accessing conflict of LISAv2 test log. If it happens on key logs which relates to test result parsing, it may cause the status of results are not shown correctly.
We’re migrating LISAv2 test cases to current LISA by test case priority. We will keep t0 to tx runbooks update to date. When test cases migrated, they will be included in current LISA, and remove from LISAv2. It’s transparent when running LISA tests.
