Hi all,

Thanks for Chris Brand’s enhancement suggestion about platform-specific tests.

I’m enabling out-of-tree build mode of platform specific test suites with tf-m-tests.

Currently I have proposed the following changes:

• [TF-M patch]
• [tf-m-tests patch]

My proposal supplies a flexible interface for partners to out-of-tree build local tests. With this new feature,

• Partners can perform local test quickly during development to improve test efficiency
• Partners can maintain local test code outside tf-m-tests repo in case of confidential information or IP issues.

I also put an out-of-tree example test source code into tf-m-extras repo and a document in TF-M repo:

• [tf-m-extras patch]
• [TF-M patch doc]

This example indicates that platform-specific tests can be integrated with tf-m-tests, without following tf-m-tests structure or definitions.

The document introduces the usage and coding guide of this new feature.

PS: If partners would like to upstream platform specific test code, we will be glad to create a specific folder under tf-m-tests repo as Chris Brand suggested.

I’d be grateful if you can take a look at the patch sets above. Any suggestion or comment is welcome.

Best Regards

Jianliang Shen
