Public functions

runWithTimingDisabled

Added in 1.0.0

inline fun <T : Any?> runWithTimingDisabled(block: () -> T): T

Disable measurement for a block of code.

Used for disabling timing/measurement for work that isn't part of the benchmark:

• When constructing per-loop randomized inputs for operations with caching,

• Controlling which parts of multi-stage work are measured (e.g. View measure/layout)

• Per-loop verification

import androidx.benchmark.junit4.measureRepeated

@Test
fun bitmapProcessing() =
    benchmarkRule.measureRepeated {
        val input: Bitmap = runWithTimingDisabled { constructTestBitmap() }
        processBitmap(input)
    }
