<pre>After looking into it, I found that the test is expecting to receive a
GL_INVALID_ENUM error when calling glCompressedTexSubImage2D() with target
different than GL_TEXTURE_2D and GL_TEXTURE_CUBE_MAP_*. The test calls
glCompressedTexSubImage2D() with target = 0.
By looking at OpenGL ES 3.0 spec, it says in section 3.8.3 "Texture Image
Specification"
"void CompressedTexSubImage2D (enum target, int level, int xoffset, int
yoffset, sizei width, sizei height, enum format, sizei imageSize, const void
*data );
[...]
"The target, level, xoffset, yoffset, zoffset, width, height, and depth
parameters have the same meaning as in TexSubImage2D and TexSubImage3D."
And TexSubImage2D() part says:
"The target arguments of TexSubImage2D and CopyTexSubImage2D must be one of
TEXTURE_2D, TEXTURE_CUBE_MAP_POSITIVE_X, TEXTURE_CUBE_MAP_NEGATIVE_X,
TEXTURE_CUBE_MAP_POSITIVE_Y, TEXTURE_CUBE_MAP_NEGATIVE_Y,
TEXTURE_CUBE_MAP_POSITIVE_Z, or TEXTURE_CUBE_MAP_NEGATIVE_Z,"
Also from the same spec, section 2.5 "GL Errors"
"If a command that requires an enumerated value is passed a symbolic constant
that is not one of those specified as allowable for that command, the error
INVALID_ENUM is generated."
This is a snip of the test output:
<Section Name="" Description="GL_INVALID_ENUM is generated if target is
invalid.">
<Text>glCompressedTexSubImage2D(0x00000000, 0, 0, 0, 0, 0, 0x00009274, 0,
0x0000000000000000);</Text>
<Text>glGetError();</Text>
<Text>// GL_NO_ERROR returned</Text>
<Text>// ERROR: expected GL_INVALID_ENUM</Text>
</Section>
Hope this helps,
Sam</pre>
