+/**
+ * Only works in test/cov command with `espower-typescript`.
+ *
+ * Fix bug that error stack gives incorrect line number and column number in unit testing.
+ *
+ * ### Reason
+ *
+ * `espower-typescript` combines the sourceMap of `ts-node` and `power-assert` and return a new sourceMap
+ *  for supporting `power-assert`. But `source-map-support` receives old sourceMap when handling the code because
+ *  `ts-node` cache its sourceMap in `retrieveFile` method: https://github.com/TypeStrong/ts-node/blob/master/src/index.ts#L218
+ *
+ * ```typescript
+ * // Install source map support and read from memory cache.
+ * sourceMapSupport.install({
+ *   environment: 'node',
+ *   retrieveFile: function (path) {
+ *       return memoryCache.outputs[path];
+ *     }
+ * });
+ * ```
+ *
+ * ### Solution
+ *
+ * Overwriting the `retrieveFile` method of `source-map-support` in `egg-bin test` to return a correct sourceMap for code.
+ *
+ *
+ * https://github.com/eggjs/egg-bin/pull/107
+ * https://github.com/power-assert-js/espower-typescript/issues/54
+ *
