From d201506cca782c54309b488170623094f252aab5 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 15 Jan 2016 11:15:24 -0700 Subject: test/py: Implement pytest infrastructure This tool aims to test U-Boot by executing U-Boot shell commands using the console interface. A single top-level script exists to execute or attach to the U-Boot console, run the entire script of tests against it, and summarize the results. Advantages of this approach are: - Testing is performed in the same way a user or script would interact with U-Boot; there can be no disconnect. - There is no need to write or embed test-related code into U-Boot itself. It is asserted that writing test-related code in Python is simpler and more flexible that writing it all in C. - It is reasonably simple to interact with U-Boot in this way. A few simple tests are provided as examples. Soon, we should convert as many as possible of the other tests in test/* and test/cmd_ut.c too. The hook scripts, relay control utilities, and udev rules I use for my own HW setup are published at https://github.com/swarren/uboot-test-hooks. See README.md for more details!
