我用Mocha测试React组件。其中一些组件连接到react-apollo商店。所以，我需要使用GraphQL查询和突变。
我使用mocha-graphql-register。有了这个库，Mocha就会看到GraphQl查询和像字符串一样的变异。
这是我的测试文件（ flow-list.spec.js ）：
const data = {
loading: false,
"flows": [
{
"id": "Rmxvd05vZGU6MQ==",
"name": "NameOfFlow",
}
],
"applications": [
{
"name": "NameofApp"
}
],
"flowModes": [
{
"name": "Flow Mode Foo"
}
],
"flowTypes": [
{
"name": "Flow Type Foo"
}
],
"bls": [
{
"name": "BL Foo"
}
]
};
describe('<FlowList/>', () => {
it('Must print table with 7 columns', () => {
const wrapper = shallow(
<FlowList data={data}/>
);
expect(tableHeaderColumns).to.have.length(7);
});
});
但是，当我运行npm test时出错。在react-apollo中似乎是一个错误......我无法理解它，也不知道如何解决它。
在npm测试后面，我运行命令：
cross-env NODE_ENV=production mocha --compilers graphql:mocha-graphql-register,js:babel-register,:tools/style-and-images-compiler.js tests/index.js
这里是npm test的跟踪日志：
> cross-env NODE_ENV=production mocha --compilers graphql:mocha-graphql-register,js:babel-register,:tools/style-and-images-compiler.js tests/index.js
ENV setup is done !!!
Warning - the `printer` exports from `graphql-tag` will be removed in the next major version.
See https://github.com/apollographql/graphql-tag/issues/54 for more information.

答案 0 :(得分：0)
呃......我错过了导入＆＃39; gql＆＃39;来自graphql-tag库。
在我的代码中，我需要使用GraphQL查询和这样的突变：
git reset --soft <SHA OF PARENT OF BAD COMMIT>
它现在有效。
