+# Suggest using `toHaveLength()` (`prefer-to-have-length`)
+
+In order to have a better failure message, `toHaveLength()` should be used upon
+asserting expectations on objects length property.
+
+## Rule details
+
+This rule triggers a warning if `toBe()`, `toEqual()` or `toStrictEqual()` is
+used to assert objects length property.
+
+```js
+expect(files.length).toBe(1);
+```
+
+This rule is enabled by default.
+
+### Default configuration
+
+The following patterns are considered warnings:
+
+```js
+expect(files.length).toBe(1);
+
+expect(files.length).toEqual(1);
+
+expect(files.length).toStrictEqual(1);
+```
+
+The following pattern is not warning:
+
+```js
+expect(files).toHaveLength(1);
+```
