angularjs - 在套件运行期间努力保持对表格单元格的引用

Question

我试图从一行上的表格单元格中读出值，以按预期检查值是否匹配。

我面临的情况是 Protractor 无法获取我感兴趣的特定单元格的文本，因为它找不到我正在查询的单元格。

这是我的测试套件步骤:

beforeAll(function() {
    common.journeyValidationBtn.click();
    helper.waitForUrlToContain('journey-validation');
    helper.waitForElementToHide(common.spinner);
    common.fabBtn.click();
    helper.waitForPresenceOf(common.calculateBtn);
    common.runCalculation(secondaryPeriod);
    helper.waitForPresenceOf(common.fabBtn, 30000);
    helper.waitForElementToHide(common.spinner);
    common.selectComparisonPeriod(initialPeriod);
    helper.waitForTableRows(page.reimbursementCalculations).then(function() {
        console.log('*** Table Rows Found - promise resolved ***');
        page.reimbursementCalculations.count().then(function(count){
            console.log('*** Number of Table Rows Found - ' + count + ' ***');
            row = page.reimbursementCalculations.first();
            cells = row.all(by.css('td'));
            cells.count().then(function(cellCount){
                console.log('*** Number of Table Cells Found - ' + cellCount + ' ***');
                cells.get(0).getText().then(function(text){
                    console.log('*** First Table Cell Text - ' + text + ' ***');
                });
            });
        });
    }, function(reason){
        console.log('*** Table Rows Not Found - promise rejected ***');
        console.log(reason);
    });
});
it('Then I should get more than one cell returned', function() {
    expect(cellCount.count()).toBeGreaterThan(0);
});

在运行测试时，我看到一些 Jasmine 超时错误，然后是我期望的失败，它无法对在 beforeAll 块中分配的单元格变量调用 count() 。也许这个超时与我所看到的有关，但我正在努力进一步调试。

从我添加的控制台日志中可以看出， Protractor 能够找到一行并检索我分配给我的单元格属性的单元格(控制台日志显示 11 个单元格)，但似乎这在预期的时候变得不确定跑。 cell 属性也在我的 beforeAll 之外定义，所以我认为在执行期望检查时这将保持分配状态而不是未定义。

这给我以后的测试带来了问题，我想读取和检查每个单元格的值。

我觉得我在做一些根本错误的事情，有人可以帮忙吗？

谢谢

默认 Jasmine beforeAll , beforeEach , afterEach , afterAll和 it将期望超时变量作为第二/第三个参数。尽管没有明确提及您的示例，但请阅读 timeout-parameter of jasmine here

尽管您的回调来自您的辅助函数，但我的假设是，您的原因函数使其失败，因为 Jasmine 可能不支持 JavaScript 的所有方面。

尝试没有原因功能:

beforeAll(function() {
    //all your test code

    }); //don't add ", function(reason){etc});
});
it('Then I should get more than one cell returned', function() {
    expect(cells.count()).toBeGreaterThan(0);
});

进一步说明，在这里你忘记重新设置“计数”，这就是为什么你的表格行和表格单元格是相同的数字:

cells = row.all(by.css('td'));
cells.count().then(function(count2){ //Here the "count" is missing
    console.log('*** Number of Table Cells Found - ' + count2 + ' ***');

更新

你是对的，回调是你自己的函数，而不是助手。

我现在刚刚看到你有错误“无法读取'undefined'的属性'count'”。因此您的对象 page.reimbursementCalculations可能是空的。

目前这两行记录了相同的变量:

console.log('*** Number of Table Rows Found - ' + count + ' ***');
console.log('*** Number of Table Cells Found - ' + count + ' ***');
