Add extra file to android VTS test

Question

I am wondering how I can add an arbitrary file into a VTS test module for android? My test binary would need to access that file when running on the target device.

Looking at many cc_test tests in the android repo, I can find many tests, but the PushFilePreparer of them is only copying one item - the compiled binary.

I tried including a file in by module dir and making a PushFilePreparer rule for it, but the file cannot be found. -> Local source file 'data.dat' does not exist [...].

Is there some prebuilt line I need to add in the Android.bp file? (The file shall only be used for testing).

The test's xml file (I tried adding the line for data.dat):

<?xml version="1.0" encoding="utf-8"?>

<configuration description="Runs TestNothing test.">
    <option name="test-suite-tag" value="ap" />
    <option name="test-suite-tag" value="ap-native" />

    <target_preparer class="com.android.tradefed.targetprep.RootTargetPreparer">
    </target_preparer>

    <target_preparer class="com.android.tradefed.targetprep.PushFilePreparer">
        <option name="cleanup" value="true" />
        <option name="push" value="Test00->/data/local/tmp/Test00" />
        <option name="push" value="data.dat->/data/local/tmp/data.dat" />
    </target_preparer>

    <test class="com.android.tradefed.testtype.GTest" >
        <option name="native-test-device-path" value="/data/local/tmp" />
        <option name="module-name" value="Test00" />
        <option name="native-test-timeout" value="6000" />
    </test>
</configuration>

The Android.bp build file:

cc_test {
   name: "Test00",
   defaults: ["VtsHalTargetTestDefaults"],
   cflags: ["-DARG=1"],
   srcs: [
   "TestNothing0.cpp",
   ],
   static_libs: [
       "libgmock",
   ],
   test_suites: ["general-tests", "vts"],
   test_config: "TestNothing0.xml",
