测试包中是否有正则表达式匹配器

Question

我有<span class="percent-complete-bar" style="width: 85%; background: green;"></span>之类的元素，我想检查style属性是否包含width: xx%; r'width: \d{1,3}%;'

等正则表达式

await bar.attributes['style']

返回width: 85%; background: green;

Answer 1

expect(await bar.attributes['style'], matches(r'width: \d{1,3}%;'));
