```yml
|
|
tests:
|
|
- text: <code>quotient</code>的值应该等于<code>2.2</code>。
|
|
testString: assert(quotient === 2.2);
|
|
- text: 使用<code>/</code>运算符将 4.4 除以 2。
|
|
testString: assert(/4\.40*\s*\/\s*2\.*0*/.test(code));
|
|
- text: quotient 变量应该只被赋值一次。
|
|
testString: assert(code.match(/quotient/g).length === 1);
