javascript - Mocha 中的异步功能

收到有关尝试断言测试用例的错误消息的问题

AssertionError: expected [Function] to throw an error
at Context.it (test\index.js:24:80)

if (configVms.rts) {
describe('Real Time Services', () => {
    for(let rtsConfig of configVms["rts"].rtsConfig) {
        it(`Real Time Services endpoints for guid ${rtsConfig.resourceId} on ${rtsConfig.platformType} platform`, async () => {
            expect(async () => await realTimeServices.main(rtsConfig)).to.throw('Host rejected');
        });
    }});
}

最佳答案

to.throw仅适用于同步功能。
在您的情况下，我建议添加chai-as-promised插件并更改测试：

if (configVms.rts) {
describe('Real Time Services', () => {
    for(let rtsConfig of configVms["rts"].rtsConfig) {
        it(`Real Time Services endpoints for guid ${rtsConfig.resourceId} on ${rtsConfig.platformType} platform`, async () => {
            await expect(realTimeServices.main(rtsConfig)).to.be.rejectedWith('Host rejected');
        });
    }});
}
