Functions

```
bool IsEventSignalled (const zx::event & event, zx_signals_t signal)
```
Synchronously checks whether the event has signalled any of the bits in

|signal|.

Defined at line 12 of file ../../src/ui/lib/escher/test/flib/util.cc
```
zx::event CopyEvent (const zx::event & event)
```
Create a duplicate of the event.

Defined at line 18 of file ../../src/ui/lib/escher/test/flib/util.cc
```
Escher * GetEscher ()
```
Must call during tests, only if !VK_TESTS_SUPPRESSED().

|escher::test::EscherEnvironment::RegisterGlobalTestEnvironment()| should be already called.

(Generatlly this should be called before RUN_ALL_TESTS() is invoked in |run_all_unittests.cc|.)

Defined at line 58 of file ../../src/ui/lib/escher/test/common/gtest_escher.cc
```
std::unique_ptr<Escher> CreateEscherWithProtectedMemoryEnabled ()
```
This function must be called after we set up the global EscherEnvironment, i.e. inside test body

functions.

Defined at line 63 of file ../../src/ui/lib/escher/test/common/gtest_escher.cc
```
bool GlobalEscherUsesSwiftShader ()
```
Checks if the global Escher environment uses SwiftShader as its physical

device. This is used in macro SKIP_TEST_IF_ESCHER_USES_DEVICE().

Defined at line 91 of file ../../src/ui/lib/escher/test/common/gtest_escher.cc
```
bool GlobalEscherUsesVirtualGpu ()
```
Checks if the global Escher environment uses an Virtual GPU as its physical

device (for example, on FEMU). This is used in macro

SKIP_TEST_IF_ESCHER_USES_DEVICE().

Defined at line 79 of file ../../src/ui/lib/escher/test/common/gtest_escher.cc
```
bool GlobalEscherUsesSoftwareGpu ()
```
Defined at line 85 of file ../../src/ui/lib/escher/test/common/gtest_escher.cc
