     1 /**
     2  * Helper to test CodeMirror highlighting modes. It pretty prints output of the
     3  * highlighter and can check against expected styles.
     4  *
     5  * Mode tests are registered by calling test.mode(testName, mode,
     6  * tokens), where mode is a mode object as returned by
     7  * CodeMirror.getMode, and tokens is an array of lines that make up
     8  * the test.
     9  *
    10  * These lines are strings, in which styled stretches of code are
    11  * enclosed in brackets `[]`, and prefixed by their style. For
    12  * example, `[keyword if]`. Brackets in the code itself must be
    13  * duplicated to prevent them from being interpreted as token
    14  * boundaries. For example `a[[i]]` for `a[i]`. If a token has
    15  * multiple styles, the styles must be separated by ampersands, for
    16  * example `[tag&error </hmtl>]`.
    17  *
    18  * See the test.js files in the css, markdown, gfm, and stex mode
    19  * directories for examples.
