Selenium WebDriver timing implementing JavaScript-heavy applications leading to inconsistent test results
I'm working with intermittent timing issues while using Selenium WebDriver with a JavaScript-heavy application built on Angular. There are certain elements that only appear after specific API calls, and this is causing my tests to unexpected result due to elements not being visible or interactable when Selenium tries to access them. For instance, the button I need to click is often not available right after the page loads, resulting in `ElementNotVisibleException` errors. I've tried implementing explicit waits using `WebDriverWait`, but the timing still seems flaky. Here's a snippet of what I've implemented: ```java WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10)); WebElement myButton = wait.until(ExpectedConditions.elementToBeClickable(By.id("my-button-id"))); myButton.click(); ``` Unfortunately, I still get inconsistent results, where sometimes the button is not clickable, leading to a timeout exception, and other times it works perfectly. Additionally, I tried using `ExpectedConditions.visibilityOfElementLocated`, but this didn't improve the situation either, as the button was sometimes visible in the DOM but not interactable. I also considered adding a sleep statement before the interaction, which is against best practices, but I was desperate and added `Thread.sleep(2000);` as a last resort, yet it didn’t solve the question. I suspect the scenario might also relate to how Angular manages its UI updates. Given this context, does anyone have suggestions for handling such dynamic elements in a more reliable way? Are there specific strategies or patterns I could apply to ensure that the button is always interactable when I need to click it? I’m using Selenium version 4.0.0 and ChromeDriver version 95.0.4638.54. Any insights would be much appreciated!
