Javascript 访问酶&;中嵌套按钮的onClick fn;反应钩
本质上,我试图测试当我的按钮被点击时,我的模态是否打开&我是一个开玩笑的人 我在访问按钮上的道具时遇到了一个问题&我不确定这是因为它嵌套在第三方包中,还是因为我没有正确地将它导入到测试中。请参阅下面我的压缩(ish)代码,因为我不打算在CodePen上重新创建代码 DataTable.jsxJavascript 访问酶&;中嵌套按钮的onClick fn;反应钩,javascript,reactjs,jestjs,enzyme,Javascript,Reactjs,Jestjs,Enzyme,本质上,我试图测试当我的按钮被点击时,我的模态是否打开&我是一个开玩笑的人 我在访问按钮上的道具时遇到了一个问题&我不确定这是因为它嵌套在第三方包中,还是因为我没有正确地将它导入到测试中。请参阅下面我的压缩(ish)代码,因为我不打算在CodePen上重新创建代码 DataTable.jsx const UploadDownloadComponent = ({ handleOpen }) => ( <UploadDownloadButtonContainer> &l

从“React”导入React;
从“酶”导入{configure,mount,shallow};
从“酶-适配器-反应-16”导入适配器;
从“./components/MemberView/DataTable”导入{Table};
从“./components/MemberView/UploadModal”导入{UploadModal};
从“反应模态”导入模态;
配置({adapter:newadapter()});
描述(“,()=>{
const wrapper=mount();
//使用.upDate()是我通过此测试的唯一方法
它(“应该有上传按钮”,()=>{
const uploadButton=wrapper.find(“#批量添加按钮”).update();
expect(uploadButton).toHaveLength(1);
});
//这过去了
它(“呈现上传模式”,()=>{
常量upModal=浅();
expect(upModal.find(Modal)).toHaveLength(1);
});
它(“状态更改时打开上载模式”,()=>{
const modal=mount();
expect(modal.find(modal.prop)(“isOpen”).toBe(false);
const uploadButton=wrapper.find(“#批量添加按钮”).update();
expect(uploadButton.length).toEqual(1);
//这就是我的测试失败的地方,因为它无法模拟单击uploadButton
上传按钮。模拟(“点击”);
//如果我将其更改为:
wrapper.find(“#批量添加按钮”).simulate(“单击”)
//我的错误消息说应该找到1个节点)。
//我没走这么远
expect(modal.find(modal.prop)(“isOpen”).toBe(true);
});
});
如果有什么不同的话,我也在用钩子
欢迎提供任何帮助/建议
谢谢在访问道具时,以下方法对我很有效
expect(modal.find(Modal).props().isOpen).toBe(false);
希望这能奏效
