selectDeviceForQueryTypeOrSkipTestCase

• selectDeviceForQueryTypeOrSkipTestCase(types): void

• Convenience function for selectDeviceOrSkipTestCase. Select a device with the features required by these query type(s). If the device creation fails, then skip the test case.

  Parameters

  • types: GPUQueryType | GPUQueryType[]

  Returns void

selectDeviceForTextureFormatOrSkipTestCase

• selectDeviceForTextureFormatOrSkipTestCase(formats): void

• Convenience function for selectDeviceOrSkipTestCase. Select a device with the features required by these texture format(s). If the device creation fails, then skip the test case.

  Parameters

  Returns void

selectMismatchedDeviceOrSkipTestCase

• selectMismatchedDeviceOrSkipTestCase(descriptor): void

• Some tests need a second device which is different from the first. This requests a second device so it will be available during the test. If it is not called, no second device will be available.

  If the request isn't supported, throws a SkipTestCase exception to skip the entire test case.

  Parameters

  • descriptor: DeviceSelectionDescriptor

  Returns void

skip

• skip(msg): never

• Throws an exception marking the subcase as skipped.

  Parameters

  • msg: string

  Returns never

skipIf

• skipIf(cond, msg?): void

• Throws an exception making the subcase as skipped if condition is true

  Parameters

  • cond: boolean

  • msg: string | (() => string) = ''

  Returns void

• skipIfCopyTextureToTextureNotSupportedForFormat(...formats): void

• Parameters

  • Rest ...formats: (undefined | GPUTextureFormat)[]

  Returns void

skipIfDepthTextureCanNotBeUsedWithNonComparisonSampler

• skipIfDepthTextureCanNotBeUsedWithNonComparisonSampler(): void

• Skips this test case if a depth texture can not be used with a non-comparison sampler.

  Returns void

skipIfInterpolationTypeOrSamplingNotSupported

• skipIfInterpolationTypeOrSamplingNotSupported(__namedParameters): void

• Skips test if the given interpolation type or sampling is not supported.

  Parameters
