Overview

Selenium Testing Library

Testing Library selectors available as Selenium locators for Kotlin/Java.

Why? When I use Selenium, I don't want to depend on ids, classes, and similar. I'm a fan of the Testing Library because it encourages "testing as a user":

The more your tests resemble the way your software is used, the more confidence they can give you.

ℹ️ To set it up, pick the library's latest version at Maven Central. Then, copy the declaration for your build tool.

These are just a few examples. There are unit tests that illustrate all the usages.

Core API

The core API contains the selectors which are mapped into Selenium locators:

driver.findElements(ByAltText("first name"))
driver.findElements(ByDisplayValue("/john/i", matchTextBy = REGEX))
val active = driver.findElements(ByLabelText("active"))
val input = driver.findElements(ByPlaceholderText("first name", exact = false))
val firstName = input.text
driver.findElements(ByRole("heading", name = "/as a user/i", matchTextBy = REGEX))
val panel = driver.findElements(ByTestId("test-id"))
panel.click()
driver.findElements(ByText("present", exact = false, selector = "span"))
driver.findElements(ByTitle("title 1"))

An alternative API that does not use Selenium locators:

val result1 = driver.queryBy(AltText, "alt 1", mapOf("exact" to false))
val result2 = driver.getBy(DisplayValue, "incredibles")
val result3 = driver.queryAllBy(LabelText, "label x")
val result4 = driver.getAllBy(Role, "listbox")

ℹ️ All the Testing Library core functionality is available.

User Interactions

The Testing Library's user-event is also mapped:

driver.user.click(active)
driver.user.dblClick(panel)
driver.user.type(input, "foobar")
driver.user.selectOptions(driver.findElement(ByRole("listbox")), "C")

ℹ️ user-event's JavaScript only loads if it's used.

ByRole: can't use regex in name field
The example from the readme driver.findElements(ByRole("heading", name = "/as a user/i", matchTextBy = REGEX)) doesn't work.

The matchTextBy param is applied to the role parameter and not to name, so the resulting call will be (heading, { name: '/as a user/i' }) instead of (heading, { name: /as a user/i })

Test to reproduce this:

@Test fun `role with regex in name parameter`() { driver.render( """<h1>something as a user something</h1>""" ) val result = driver.findElements(ByRole("heading", name = "/as a user/i", matchTextBy = REGEX)) assertEquals(expected = "something as a user something", result.single().accessibleName) }

Can't map jest-dom matchers that receive parameters

this part of the API - jest-dom - has hit a roadblock as I try to be able to execute jest-dom as a standalone so I can execute it from Selenium. more info
