16// Integration test for the R8 retracing tool.
17
18// The retracing tool is a developer tool and part of the build tools.
19// The following tests are structured so that the app and retrace tool
20// are invoked exactly as a normal build would. The check that they
21// produce the correct result is then postponed to a test so that a
22// retrace tool failure will not result in a build failure.
23
24// Rule to dexdump the content of a sample app.
25// The dexdump is used to simulate a raw stack trace from the app.
