| Description: |
| |
| Valid cases compile and run a program that perform the implicit conversion |
| operation in either vertex and fragment shader. Results are checked against |
| reference values in the shader code and either black or white color is |
| selected based on that. The test verifies that all result pixels are white. |
| |
| Negative cases attempt to compile a shader with the invalid operation and |
| checks that the compilation in fact fails. |
