Java maven - IllegalArgumentException: Input must be set

Question

I get the following errror when I use git bash command - however when I run the test in Intellij everything works fine and test starts. Could you help ?

mvn test -Dcucumber.filter.tags="@desktop"

Intellij configuration where it works

Answer 1

The error message "java.lang.IllegalArgumentException: Input must be set" says that the issue is with the code and not with the tool or IDE. This error occurs when a null or empty input is passed into a method that is not programmed accept it. In this case, it is happening when creating an object of the FluentWait class from the org.openqa.selenium.support.ui package.

Based on the provided information, the issue seems to be related how waitForElement() method in the Utils class is implemented. This method is trying to create an object of the FluentWait class, but the input provided to this class is empty, which is causing the exception to be thrown.

To fix this issue, we need to pass the correct input parameter to the FluentWait class. In the waitForElement() method, we need to pass the WebDriver instance as a parameter to the FluentWait constructor. Here is how we can modify the code:

public static void waitForElement(WebDriver driver, WebElement element) {
    FluentWait<WebDriver> wait = new FluentWait<>(driver)
            .withTimeout(Duration.ofSeconds(30))
            .pollingEvery(Duration.ofMillis(500))
            .ignoring(NoSuchElementException.class);

    wait.until(ExpectedConditions.visibilityOf(element));
}

In this code, driver instance is being passes as a parameter to the FluentWait constructor. Along with it the element instance to the visibilityOf() method of the ExpectedConditions class is also being passed. The element instance is passed to the until() method of the wait instance. This ensures that the wait will be executed only until the element becomes visible.

Once you make the above changes, you can rerun the mvn test -Dcucumber.filter.tags="@desktop" command, and the error should be resolved.
