“ IsPresent（）”中的“其他”代码未执行。仅执行“ IF”代码。它发生的任何原因。我正在用茉莉花框架量角器。在输出中，首先代码在“ IsPresent（）”函数内执行“ If”，然后再次调用递归，我希望应该按照我从excel输入的值执行“ else”块。但是执行到此为止，当我手动关闭浏览器时，它将在“ IsPresent（）”的“ else”中打印该语句。无法确定为什么卡住并且不移动。任何建议，将不胜感激。
注意：已经使用了递归，以便可以从excel文件读取值并根据索引打印输出。
以下是我正在使用的代码：

browser.get('My App URL');
});

.getText().then(function (PID) {
console.log("PID is: " +PID);
if (PID!=value) {
console.log("Unmatched PID is: " + value + " and counter is: " + index);

答案 0 :(得分：0)
我建议使用async / await，因为它将清理您的诺言并链接then语句。在上面的代码中，有未与.then链接的promise。使用async / await应该可以清除其中的一些内容。
因此，对于初次通过，请修复为使用异步/等待。您的递归有问题，我不确定如何根据所提供的内容进行修复（以下评论中的讨论）。
您需要执行异步/等待的另一个原因是，Protractor在不久的将来将不再支持控制流。要关闭控制流（使用异步/等待），您需要在量角器配置文件中设置SELENIUM_PROMISE_MANAGER: false。
// Please be consistent with your import of by. If you are using "By"
// then do not also use "by".
export async function loop(i: number): Promise<void> {
if (i >= 1) {
// This is not locating a web element by css. You should just use a
// css selector. This can lead to brittle tests.
await element(by.css('body > app-root > app-side-menu > mat-sidenav-container > mat-sidenav > mat-nav-list > div > div > div.col-md-2 > button')).click();
// Same issue here. Documented at http://www.protractortest.org/#/style-guide
const count = await element.all(by.xpath('//*[contains(@id,"mat-dialog")]/app-error-dialog/div/div[1]/div/span')).count();
console.log(`count Value is: ${count}`);
if (count <= 0) {
const PID = await element(by.css('text[transform="translate(800.8947256481425,612.9323227754049)rotate(0)"]')).getText();
console.log("PID is: " + PID);
} else {
await element(by.xpath('//*[contains(@id,"mat-dialog")]/app-error-dialog/div/div[1]/div/span')).click();
await loop(i - 1);
}
// Not exactly sure what's going on here, I'm guessing you keep clicking
// at the same transform and the count keeps decreasing. When the i - 1 = 0,
// then break the recursion. Let's say in the first recursion, we i = 4.
// We print out all the PIDs and then when i = 1, we will click the link,
// then loop(0) and whatever loop(rows) is. After that, i = 2, we'll then
// again do loop(1) and whatever loops(rows) is.
//
// Something isn't right here. I would maybe discuss what you are doing
// html requires recursion.
await element(By.css('body > app-root > app-side-menu > mat-sidenav-container > mat-sidenav-content > app-process-view-container > div > app-process-pane > div > mat-card > nav > div > ul > li:nth-child(5) > a > div')).click();
// Much recursion. Such loops.
await loop(i - 1);
// rows = ¯\_(ツ)_/¯
await loop(rows);
}
}
请修改您的问题，以便我们了解递归部分。您点击什么？您的测试实际应该做什么。请提供更多信息。
