灵感来自：jest/no-standalone-expect

¥Inspired from: jest/no-standalone-expect

检查正则表达式是否是简单参数时，检查 unicode 宽度而不是字节数。

¥Checks that the assertion function, for example expect, is placed inside an it() function call.

在执行测试套件时，放置（和使用）expect 断言函数可能会导致意外行为。

¥Placing (and using) the expect assertion function can result in unexpected behaviors when executing your testing suite.

规则将检查以下断言调用：

¥The rule will check for the following assertion calls:

expect
assert
assertEquals

但是，该规则将忽略以下断言调用：

¥However, the rule will ignore the following assertion calls:

expect.any
expect.anything
expect.closeTo
expect.arrayContaining
expect.objectContaining
expect.stringContaining
expect.stringMatching
expect.extend
expect.addEqualityTesters
expect.addSnapshotSerializer

如果导入了断言函数，规则将检查它们是否从以下位置导入：

¥If the assertion function is imported, the rule will check if they are imported from:

"chai"
"node:assert"
"node:assert/strict"
"bun:test"
"vitest"
Deno 断言模块 URL

¥Deno assertion module URL
