我有一个要测试的简单方法:
ts文件:
policyOptions(event): void {
this.selectedPolicy = event.srcElement["value"];
this.detectFormValueChanges();
}
spec文件,我写的是
it("policyOptions function test case", () => {
const mockSelectedPolicy = {"value": "DEFAULT"};
component.policyOptions(mockSelectedPolicy);
component.detectFormValueChanges();
});
html代码:
<input id="enable" (change)="policyOptions($event)" type="radio" value="ENABLED" name="antiPhishingSelectPolicy" class="radio__input" [checked]="selectedPolicy==='ENABLED'">
我遇到错误:"value is undefined"
。我究竟做错了什么?我该如何解决?
我刚开始接触角度测试,因此发现单元测试很难克服。请帮忙。

我找到了解决方案,虚拟数据格式不正确。这是测试用例:
it("policyOptions method test case, when DEFAULT is the value", () => {
const testevent = {
srcElement: {
value: "DEFAULT",
},
};
component.policyOptions(testevent);
expect(component.selectedPolicy).toEqual("DEFAULT");
component.policyOptions(testevent);
});
