protected function IconTestCase::assertIconContentsEqual

Compare the contents of two SVG icons for equality.

This function compares the inner contents of an SVG while ignoring some differences on the <svg> tag, like the default classes added by theme_icon() and the aria-hidden="true" added when no alt text is used.

Parameters

string $svg1: The first SVG content to compare.

string $svg2: The second SVG contents to compare.

string $message: The message to display along with the assertion.

Return value

boolean: TRUE if the assertion succeeded, FALSE otherwise.
