To this end, we can use a custom Explicit Wait. So, we probably want to start looking for a matching toast before it pops up, so we're sure we don't miss it. This is great, but as we've mentioned already, toasts are a time-sensitive phenomenon. Also read: All You Need to Know About Appium Mobile Testing Finally, we call executeScript as the way of accessing the mobile: method. If we set isRegexp to true, then we can look for toast messages using more advanced criteria, limited only by what we can express in a regular expression. This method takes two parameters: the text we want to look for, and a flag which tells Appium whether this text is in the form of a bare string or a regular expression.
Like all mobile: methods, we first need to construct a map of our arguments. Since I've already got the plumbing hooked up in The App, I can just write myself a handy little helper method that will display toasts for me from my test code:ĭriver.executeScript("mobile: isToastVisible", args)
In inflate method first parameter is the layout resource ID and the second is the root View.

I could add some behavior in my app that produces toasts, like a real app would, but instead I'm going to rely on another cool feature of the Espresso driver we've covered in the past - calling app-internal methods. Steps for Implementation of Custom Toast In Android: Step 1: Firstly Retrieve the Layout Inflater with getLayoutInflater () (or getSystemService ()) and then inflate the layout from XML using inflate (int, ViewGroup). Also check: Simulating Incoming Phone Calls on Androidįirst, we need a way to actually produce toast messages we can use for testing. Luckily, with the advent of the Espresso driver, we have the ability to match text against on-screen toasts! Let's see how it all works.

From the perspective of the Android Accessibility layer, toast messages aren't visible! If you try to get the XML source from an Appium session while a toast is present on screen, you won't find its text anywhere. Of course, toast messages can prove a challenge for automation, not just because of their ephemeral nature. Check out: What Appium Users Need to Know about Android Activities and Intents Your app might complete a background task while the user is playing a game, and with toasts you are able to convey this information without taking the user away from their present context.

Then, clear the interval by using clearInterval.įinally, in the onNewToast(), check if the duration is passed and set it to the timeOut variable.These are called toast messages, and are an important tool for Android app designers, because they don't steal focus from the current activity. In the closeToast(), set the message to null and, again, set the timeOut variable to 4,000 milliseconds. it will display for 7 sec ( 3.5 sec + 3.5 sec) This hack doesn't seem to work any longer. similarly, call the show () with LONGDELAY twice will enqueue same toast again.
it will display for 4 sec ( 2 sec + 2 sec). If it becomes 0, which means it ran four times, we're calling the closeToast function. Call the show () with SHORTDELAY twice will enqueue same toast again. We've also made it equal to the timeOutRef varible declared earlier, each time reducing 1,000 milliseconds from the timeOut state variable. Here, we'll use the setInterval function to run every 1,000 milliseconds. It's required to create a ref because we'll use it at different places in our code. We've also created a ref with the name timeOutRef. Here, we'll use a new state variable called timeOut, which has an initial value of 4,000 milliseconds. So, let's add this feature in the Toast.js file. Snackbars are just like Toast messages except they provide action to interact with. Our toast message will be shown continuously, but a toast message needs to disappear after some time. Android Snackbar is an interesting component introduced by Material Design.
