/**
 * @fileoverview `OverrideTester` class.
 *
 * `OverrideTester` class handles `files` property and `excludedFiles` property
 * of `overrides` config.
 *
 * It provides one method.
 *
 * - `test(filePath)`
 *      Test if a file path matches the pair of `files` property and
 *      `excludedFiles` property. The `filePath` argument must be an absolute
 *      path.
 *
 * `ConfigArrayFactory` creates `OverrideTester` objects when it processes
 * `overrides` properties.
