Hi Derek,

A large number of python packages leverage the pytest unit test
framework for their ptest functionality.  Currently, many of the tests
have duplicate code for:
     1. Installing pytest files
     2. Declaring ptest dependencies
     3. Script for executing tests (run-ptes)

To simplify adding common pytest based ptests, added a new class
enabling base functionality.  Users can also override the location of
the pytest files in addition to using their own version of run-ptest

I think it'd make sense to use :append here as we don't want to override anything, just provide a fallback in case the ptest-python-pytest/run-ptest isn't find anywhere else. This would also allow to easily override this file by just adding the file next to the recipe, instead of having to add a FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:" in the recipe after the inherit for example.

+
+SRC_URI += "file://ptest-python-pytest/run-ptest"
+

We use append/prepend everywhere but here, should we?

+# Overridable configuration for the directory within the source tree
+# containing the pytest files
+PTEST_PYTEST_DIR ?= "/tests"
+
+do_install_ptest_python_pytest() {
+       if [ ! -f ${D}${PTEST_PATH}/run-ptest ]; then
+               install -m 0755 ${UNPACKDIR}/ptest-python-pytest/run-ptest 
${D}${PTEST_PATH}
+       fi

This means if we ever built the recipe and don't clean its WORKDIR, but update the file, it will never be updated. I don't think that's what we want. Can you explain what you're trying to prevent here by having a check for NOT installing the file?

+    if [ -d "${S}/${PTEST_PYTEST_DIR}" ]; then

Shouldn't we use UNPACKDIR for file:// SRC_URI in master?

Cheers,
Quentin
