16 INTRODUCTION
17
18 The Android theme tests ensure that the Holo and Material themes have not been
19 modified. They consist of API-specific sets of reference images representing
20 specific themes and widgets that must be identical across devices. To pass the
21 theme tests, a device must be able to generate images that are identical to the
22 reference images.
23
24 NOTE: Reference images should only be updated by the CTS test maintainers. Any
25 modifications to the reference images will invalidate the test results.

30 I. Generating reference images (CTS maintainers only)
31
32 Reference images are typically only generated for new API revisions. To
33 generate a new set of reference images, do the following:
34
35 1. Connect one device for each DPI bucket (ldpi, xxxhdpi, etc.) that you wish
36 to generate references images for. Confirm that all devices are connected
37 with:
38
39 adb devices
40
41 2. Image generation occurs on all devices in parallel. Resulting sets of
42 reference images are saved in assets/<api>/<dpi>.zip and will overwrite
43 any existing sets. Image generation may be started using:
44
45 .cts/hostsidetests/theme/generate_images.sh
46
47 A complete collection of reference images for a given API revision must include
48 a set for each possible DPI bucket (tvdpi, xxhdpi, etc.) that may be tested.

51 II. Building theme tests
52
53 1. If you have not already built the CTS tests, run an initial make:
54
55 make cts -j32
56
57 2. Subsequent changes to the theme tests, including changes to the reference
58 images, may be built using mmm:
59
60 mmm cts/hostsidetests/theme -j32
61
62
63 III. Running theme tests
64
65 1. Connect the device that you wish to test. Confirm that is is connected with:
66
67 adb devices
68
69 2. Run the theme tests using cts-tradefed:
70
71 cts-tradefed run cts -c android.theme.cts.ThemeHostTest
72
73 3. Wait for the tests to complete. This should take less than five minutes.
