我正在尝试编写一个测试异步方法的 jest 测试用例,我想传入done()参数,以便 jest 在结束测试之前等待它被触发,但是,我不确定把它放在哪里。
有任何想法吗?
const testcases = [
[
'Crew',
[1,2,3],
Enum.Level1
],
[
'Staff',
[4,5,6],
Enum.Level2
]
];
test.each(testcases )(
'Should be able to load differing cases %p',
(
typeName: string,
initalVals: string[],
type: LevelType
) => {
// some call that updates mobx store state
when(
() => mobxstoreProperty.length == initalVals.length,
() => {
// my assertions
done();
}
);
}
);

对于单个笑话测试,我可以这样做:
test('my single test', done => {
// some call that updates mobx store state
when(
() => mobxstoreProperty.length == initalVals.length,
() => {
// my assertions
done();
}
);
});

只是不确定当我使用该test.each方法时该怎么做。
我使用命名参数,并且可以将该done()方法添加为最后一个函数参数。例如像这样:
const testcases: {
typeName: string;
initalVals: string[],
type: LevelType
}[] = [
{
typeName: 'Crew',
initalVals: [1,2,3],
type: Enum.Level1
},
{
typeName: 'Staff',
initalVals: [4,5,6],
type: Enum.Level2
},
];
test.each(testcases)(
'Should be able to load differing cases %p',
// Must use `any` for `done`, as TypeScript infers the wrong type:
({typeName, initalVals, type}, done: any) => {
// some call that updates mobx store state
when(
() => mobxstoreProperty.length == initalVals.length,
() => {
// my assertions
done();
}
);
}
);

我还没有测试您是否可以将done()方法添加为带有数组参数的最后一个参数,但也许这也有效。
