In the example shown, we have a list of T-shirts that includes color and size. However, the size is abbreviated as "S" for small and "L" for large. Lets say you want to write a formula to expand these abbreviations and show either the word "Small" or "Large" in column E. In other words:. In the example, we need to test cells in column D to see what they contain, so the formula we are using in cell E5 is:. This works fine for two conditions, but what if we have a third condition?
In that case, we need to extend the formula with another IF statement. We put the second IF statement, replacing the false result. This technique is called "nesting", since we are placing on function inside another. More than one condition can be tested by nesting IF functions Formulas are the key to getting things done in Excel. You'll also learn how to troubleshoot, trace errors, and fix problems.

Generic formula. Context In the example shown, we have a list of T-shirts that includes color and size. In other words: If a cell in column D contains "S", return "Small".
If a cell in column D contains "L", return "Large". This is a perfect application of the IF function. Related formulas. If you want to do something specific when two or more conditions are TRUE, you can use the IF function in combination with the AND function to evaluate conditions with a test, then take one action if the r esult is TRUE, and optionally doIt supports desktop, mobile, remote and cloud browsers UI or headless.
You do not need WebDriver or any other testing software. Install TestCafe with one command, and you are ready to test. TestCafe is free to use under the MIT license.
Plugins provide custom reports, integration with other tools, launching tests from IDE, etc. You can use the plugins made by the GitHub community or make your own. TestCafe automatically waits for page loads and XHRs before the test starts and after each action.
It also features smart test actions and assertions that wait for page elements to appear. You can change the maximum wait time. If elements load faster, tests skip the timeout and continue. You can also use TypeScript if you prefer a strongly typed language.
TestCafe reports JS errors that it finds on the webpage. Tests automatically fail because of that. However, you can disable this. TestCafe can open multiple instances of the same browser to run parallel tests which decreases test execution time.
You can combine them to implement readable tests with the PageObject pattern. You can now visually record automated test scripts. Code-free tests lower the learning curve and improve productivity.

Write your first test.TestCafe allows you to handle native browser dialogs whenever they are invoked during the test run. You can close alert and beforeunload dialogs, choose either option in confirm dialogs or provide text to type into prompt dialogs.
You can also access the history of the invoked native dialogs, so that you can determine if a certain dialog appeared or not. To handle native dialogs invoked during the test run, specify a handler function using the setNativeDialogHandler method of the test controller. You can provide a new handler at any moment by calling t. If a native dialog appears when no handler is set, the test fails with an error.
You can remove a dialog handler by passing null to the t. To handle native dialogs that appear during the page load, specify the dialog handler before the first test action.
You can control how a dialog is handled by using the handler's return values. If you return nothing, TestCafe performs default handling. The kind of the value that should be returned depends on the dialog type. See the table below for reference. You can get the history of the invoked native dialogs to check if a certain dialog appeared or not. Use the test controller's getNativeDialogHistory method for this.

I'm trying to write a script that needs to adapt it's workflow behavior depending on whether a particular browser object found by CSS selector exists or does not exist. I do not want to use a document. I need to be able to continue execution if the object is not there and I'm checking that it exists, or if the object is there and I'm checking that it does not exist, and also the cases where the object is not there and it does not exist and the object is not there and I'm checking that it does not exist.

False-negatives may occur because the test driver will immediately resolve this promise if the element does not exist yet. That is to say: if you are, for instance, clicking a button and expeting the element to appear, but during evaluation of the if-clause the element has not been rendered yet, than the clause will evaluate to false.
If evaluation would take place only a moment later, it would return true. Samuel I think the timeout mechanism caters for this. I used this sample. In my first attempt, my tests failed with follow error msg: ReferenceError: Selector is not defined. After running again the test it fails again with a new msg: An assertion method is not specified.TestCafe by DevExpress.

Click through the test scenario in a browser, and TestCafe Studio will record your actions and generate a test. You can run the recorded test in all major desktop and mobile browsers including Chrome, Firefox, Safari, Edge, and Internet Explorer in either visual or headless mode.
Assertions allow you to ensure that the web application correctly responds to user actions. At any moment during the test, you can check if an element is displayed and verify its state, content, style, position, and other properties. You can also run custom code on the tested page and confirm its return value. Includes a built-in wait mechanism that suspends test execution until the browser loads the page, completes XHR requests and displays the required page elements.
The auto-wait mechanism also extends to assertions and thus stabilizes tests when you verify the page state. Customizable timeouts allow you to fine-tune built-in wait mechanisms. When TestCafe Studio records a test, it produces different element selectors for each webpage element involved. They can rely on the element's ID, class, parents, attributes, etc. You can leave the default selector or choose another one that better suits the page structure and semantics.
You can create multiple configurations that define target browsers and additional test execution settings, and then run tests for specific configurations. TestCafe Studio displays comprehensive reports with overall results and details for each test. The Report View shows test results in a tabular form that allows you to sort and group the records, search through them, and rerun failed tests.

I've been working as a software developer for over 16 years. Throughout my career, I haven't worked on a single project where accessibility was a priority. I've worked on thousands of tickets, stories, and bug reports. Accessibility-related work rarely crossed my desk. At best, accessibility was an afterthought, something to be done later - if ever. At worst, it was an issue that no one brought up. I never paid much attention to making my websites accessible for people with certain limitations.
That all changed recently after meeting someone who's colorblind. Our conversation turned to the type of work that I do. I mentioned that I was a software developer, mostly focused on building web applications. He asked what type of sites I worked on, so I decided to show him on my smartphone. He squinted his eyes, contorting his face and twisting his head a bit. It wasn't a normal reaction, so I asked if there was something he saw on the site that made him react that way. He mentioned that he really couldn't read anything on the site because he's colorblind.
Handling Native Dialogs
The color contrast between the background and text was entirely unreadable for his eyes. This declaration was a bit of a wake-up call for me.
I never met someone with color blindness before. Admittedly, I never realized how something like a combination of colors could impact someone else negatively. After this encounter, I garnered an interest in web accessibility and how it affects others with limitations. This list of stories by the W3C Web Accessibility Initiative served as a sobering reminder that web developers and testers have the responsibility to make the web accessible to everyone.
As I learned more about accessibility, I realized that making your websites accessible can take plenty of work. There are plenty of guidelines to follow, such as:.
These guidelines are a fraction of the guidelines recommended by the latest version of the Web Content Accessibility Guidelines. With all the recommendations, it isn't straightforward to know where to begin or to stay within the guidelines. If you're interested in making your projects accessible but don't know where to begin, axe has you covered. Using axe as part of your development and testing process helps tackle most accessibility problems.
