To retrieve links via "link text" or "partial link text" the rendered content of the element has to be used. This can be the case for CSS transformations like "uppercase". bugzilla-url: https://bugzilla.mozilla.org/show_bug.cgi?id=1381519 gecko-commit: 3e204686f1b10441f48435890241dff6706d04dd gecko-integration-branch: central gecko-reviewers: ato

// These tests check that generateKey throws an error, and that
// the error is of the right type, for a wide set of incorrect parameters.

// Error testing occurs by setting the parameter that should trigger the
// error to an invalid value, then combining that with all valid
// parameters that should be checked earlier by generateKey, and all
// valid and invalid parameters that should be checked later by
// generateKey.
//
// There are a lot of combinations of possible parameters for both
// success and failure modes, resulting in a very large number of tests
// performed.
// Setup: define the correct behaviors that should be sought, and create
// helper functions that generate all possible test parameters for
// different situations.
