我们使用 git 进行版本控制,所以代码是一样的。但是,如果我生成快照,而我的同事运行测试,则它们都在快照部分失败。为什么会发生这种情况?
示例组件
import React from 'react';
import styled from 'styled-components';
import classnames from 'classnames';
import { colors } from '../../utils/css';
const ProgressIcon = ({ className, progress, color }) => (
<div className={className}>
<div className={classnames('background', color)}>
<div className={classnames('icon', progress, color)}/>
</div>
</div>
);
export const StyledProgressIcon = styled(ProgressIcon)`
width: 12.8px;
height: 12.8px;
margin: 0;
div {
margin: 0;
}
.background.white {
border: 2px solid ${colors.LG_WHITE};
}
.background.gray {
border: 2px solid ${colors.LG_GRAY_2};
}
.background {
height: 100%;
width: 100%;
border-radius: 50%;
box-sizing: border-box;
.icon {
height: 100%;
}
.icon.white {
background: ${colors.LG_WHITE};
}
.icon.gray {
background: ${colors.LG_GRAY_2};
}
.icon.full {
width: 100%;
}
.icon.half {
width: 50%;
}
.icon.empty {
width: 0;
}
}
`;
测试
import React from 'react';
import { shallow } from 'enzyme';
import { StyledProgressIcon as ProgressIcon } from '../ProgressIcon';
describe('<ProgressIcon/>',
() => {
let wrapper;
beforeEach(() => {
wrapper = shallow(<ProgressIcon progress={'full'} color={'gray'}/>);
});
it('should match the snapshot', () => {
expect(wrapper).toMatchSnapshot();
});
});
我正在比较我的同事创建的快照(其他人的测试都通过了完全相同的快照和代码。它只在我的机器上失败了)
这是日志

反之,如果我生成快照,然后我的同事进行测试。为什么会发生这种情况,我该如何解决?
最佳答案
There is a version mismatch in your styled-components lib dependency. As explained here
正是样式化组件的浅层渲染向您展示了 "isStatic": false 值
你们都需要同步你的依赖。首先
make sure that both have the same package.json.
那么做到这一点的万无一失的方法是。在你的一台电脑上
- Remove node_modules
- delete package-lock.json
- Run npm install
- Commit your package-lock.json! (ignore if no changes)
转到所有其他 PC。
- Pull in the changes to package lock json (reject all local and accept all remote changes).
- Remove node_modules.
- Run npm install.
现在运行测试并检查,快照应该相等。
关于javascript - 相同的代码在不同的机器上生成不同的快照,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/58396061/
