I tried expect-playwright, but it seems, that doesnt have all important methods and additional features, which most of you and I really need. It provides comprehensive error messages and highlights the difference and thats really awesome. Motivation. Let me show you how it looks like. expectThatDialog().isOfType(dialogType,[options]), expectThatDialog().hasMessage(message,[options]), expectThatDialog().hasValue(value,[options]), expectThatDialog().hasExactValue(value,[options]), expectThatSelector(selector).hasFocus([options]), expectThatSelector(selector).hasText(text,[options]), expectThatSelector(selector).hasClass(className,[options]), expectThatSelector(selector).hasPlaceholder(text,[options]), expectThatSelector(selector).hasAttributeWithValue(attributeName, attributeValue, [options]), expectThatSelector(selector).doesNotHaveClass(className,[options]), expectThatSelector(selector).hasValue(value,[options]), expectThatSelector(selector).hasExactValue(value,[options]), expectThatAsyncFunc(func).resolvesTo(value,[options]), expectThatSelector(selector).isVisible([options]), expectThatSelector(selector).isVisibleInViewport([options]), expectThatSelector(selector).isNotVisible([options]), expectThatSelector(selector).isNotVisibleInViewport([options]), expectThatSelector(selector).exists([options]), expectThatSelector(selector).doesNotExist([options]), expectThatSelector(selector).isChecked([options]), expectThatSelector(selector).isUnchecked([options]), expectThatSelector(selector).isEnabled([options]), expectThatSelector(selector).isDisabled([options]), expectThatSelector(selector).isReadOnly([options]). Great. It will automatically wait until a dialog is opened. Another thing I want to discuss is timeout errors. It lets you write better assertions for end-to-end testing. Another case, we have some label that has a whitespace such as space, tab, no-break space, etc. Will check if the selector has a placeholder attribute with the specified text. You can run the test above without providing the trim property and take a look at the error message, itll be like this: As demonstrated, the diff highlights feature works pretty good, and help us easily and quickly find root cause of the issue. All over, Ive come up with the idea that Id like to have something similar that we have for the WebdriverIO, but for the new Playwright Test runner. None of us likes when our tests fail due to timeout errors, so your knee-jerk reaction might be to add wait methods to avoid the timeout errors. The waiting mechanism can be customized through the optional options parameter. Almost all methods can accept element in three ways: // Using an array of page and selector. Lets consider the following test, where were expecting that the title of the page equals to the expected on: As you can see Ive provided ignoreCase property to the toHaveTitle function as a second argument.

This library provides a lot of matchers like toEqual, toContain, toMatch, toMatchSnapshot and many more: expect(success).toBeTruthy(); Playwright also extends it with convenience async matchers that will wait until the expected condition is met. Even more, we have just used our first toHaveUrl custom matcher method that could save time on end-to-end tests development. await expect([page, 'button']).toBeEnabled(); await expect(await page.$('button')).toBeDisabled(); await expect(page.$('button')).toBeDisabled(false); npx playwright test ./current-url.test.ts. Our Day 1 exploration of Playwright helped us setup and validate our local testing envrionment. Custom Message will show in Test Steps no matter whether your test pass or fail.

You just need to do three steps to start using it: 2. Selector is incorrect so expect will fail. Hope you liked the article. It also has a rich set of introspection events.

The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. can ignore case sensitive and trim values before asserting; built-in types for TypeScript and JavaScript autocompletion. This message will also display as a title in Test Steps and an error message in the Errors section of the report. // you can also use the alias expectThat: * time during which the Assert must give back the same result.
