disableSharding

[bootstraponline]

If disableSharding is true then we should skip trying to shard methods. Sharding is currently incompatible with parameterized tests on both Android and iOS.

The following iOS code will then be updated

before:

// Parameterized tests on iOS don't shard correctly.
        // Avoid changing Xctestrun file when test shards is 1.
        val generatedXctestrun = if (args.testShards == 1) {
            xcTestParsed.toByteArray()
        } else {
            Xctestrun.rewrite(xcTestParsed, methods)
        }

after:

// Parameterized tests on iOS don't shard correctly.
        // Avoid changing Xctestrun file when test shards is 1.
        val generatedXctestrun = if (args.disableSharding == 1) {
            xcTestParsed.toByteArray()
        } else {
            Xctestrun.rewrite(xcTestParsed, methods)
        }

This will also help on Android where the apk fails to be parsed by dex-test-parser.

/cc @ceaglest @paynerc once this feature lands, you'll want to set disableSharding: true when using parameterized tests. #433
