216 * timeout. Then, automatically the failed test list will be retested
217 * automatically only this number of times.
218 *
219 * - steps
220 * This property is array of testing. Each steps must have following
221 * properties at least.
222 *
223 * - func
224 * This property means function which will be called via
225 * |setTimeout|. The function cannot have params. If you need
226 * some additional parameters, you can specify some original
227 * properties for the test function. If you do so, you should
228 * document it in the testing function.
229 * - delay
230 * This property means delay time until the function to be called.
231 * I.e., the value used for the second param of |setTimeout|.
232 *
233 * And also you need one more property when you call a testing function.
234 *
235 * - description
236 * This property is description of the test. This is used for
237 * logging.
