我有下面的茉莉花测试用例,我想将函数getAllUsageCategoriesDropListElements返回的值存储到一个数组中,这样我就可以访问测试用例中的数组并用另一个数组评估它的内容。
it('Validate the Usage Category droplist values matches with the Usage Categories Table',() => {
let allUsageCategoryDropListElements: string[] = [];
additionalCostsPage.getAllUsageCategoriesDropListElements(
element => {
console.log("Text from the usage Cateory Droplist elements " + element);
allUsageCategoryDropListElements.push(element);
console.log(" from inside " + allUsageCategoryDropListElements.length);
}
);
console.log("Size of the array is " +allUsagCategoryDropListElements.length );
});
方法如下:
getAllUsageCategoriesDropListElements(evaluationFunc:(element:string)=> void):void {
E2EUtil.click(this.addAdditionalCostDialogue.usageCategoryField);
E2EUtil.waitFor(this.addAdditionalCostDialogue.usageCategoryDropListContainer);
browser.sleep(2000);
var usageCategoryFromPage: string[] = [];
element.all(by.xpath("//*[@id='usageCategory']/div/div[3]/div/ul/li[*]/span"))
.each(function (element, index) {
element.getText().then(function (text){
// console.log("text extracted is " + text);
usageCategoryFromPage.push(text);
})
})
.then(function(){
usageCategoryFromPage.forEach(evaluationFunc);
});
}
函数内部打印的数组大小适当增加,但在函数外部打印时为0。我认为这是由于异步代码执行所致。有人可以帮忙吗?我对这个打字稿世界很陌生。
答案 0 :(得分:0)
要等待运行代码,您需要正确添加TZ
和async
关键字。试试:
await
编辑:您的it('Validate the Usage Category droplist values matches with the Usage Categories Table', async () => {
let allUsageCategoryDropListElements: string[] = [];
await additionalCostsPage.getAllUsageCategoriesDropListElements(
element => {
console.log("Text from the usage Cateory Droplist elements " + element);
allUsageCategoryDropListElements.push(element);
console.log(" from inside " + allUsageCategoryDropListElements.length);
}
);
console.log("Size of the array is " +allUsagCategoryDropListElements.length );
});
不是异步的,但是您使用的是Promise。您可以对其进行更新以使其异步,然后调用函数中的getAllUsageCategoriesDropListElements
将正常工作。
尝试:
await/async
