撰寫測試

簡介

Playwright 斷言專為動態網頁建立。檢查會自動重試直到滿足必要條件。Playwright 內建自動等待，這意味著它會在執行操作之前等待元素可操作。Playwright 提供assertThat重載來撰寫斷言。

請查看下面的範例測試，了解如何使用 web first 斷言、定位器和選擇器來編寫測試。

package org.example;

import java.util.regex.Pattern;
import com.microsoft.playwright.*;
import com.microsoft.playwright.options.AriaRole;

import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

public class App {
    public static void main(String[] args) {
        try (Playwright playwright = Playwright.create()) {
            Browser browser = playwright.chromium().launch();
            Page page = browser.newPage();
            page.navigate("http://playwright.dev");

            // Expect a title "to contain" a substring.
            assertThat(page).hasTitle(Pattern.compile("Playwright"));

            // create a locator
            Locator getStarted = page.getByRole(AriaRole.LINK, new Page.GetByRoleOptions().setName("Get Started"));

            // Expect an attribute "to be strictly equal" to the value.
            assertThat(getStarted).hasAttribute("href", "/docs/intro");

            // Click the get started link.
            getStarted.click();

            // Expects page to have a heading with the name of Installation.
            assertThat(page.getByRole(AriaRole.HEADING,
               new Page.GetByRoleOptions().setName("Installation"))).isVisible();
        }
    }
}

斷言

Playwright 提供了assertThat 多載，將會等待直到預期條件被滿足。

import java.util.regex.Pattern;
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

assertThat(page).hasTitle(Pattern.compile("Playwright"));

定位器

定位器是 Playwright 自動等待和重試功能的核心。定位器代表了一種在任何時刻在頁面上找到元素的方法，並用於對元素執行操作，如 .click .fill 等。可以使用 Page.locator() 方法建立自訂定位器。

import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

Locator getStarted = page.locator("text=Get Started");

assertThat(getStarted).hasAttribute("href", "/docs/intro");
getStarted.click();

Playwright 支援許多不同的定位器，如 role text, test id 等等。了解更多關於可用定位器以及如何選擇定位器的資訊，請參閱這個深入指南。

import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

assertThat(page.locator("text=Installation")).isVisible();

測試隔離

Playwright 有一個 BrowserContext 的概念，它是一個在記憶體中隔離的瀏覽器配置檔。建議為每個測試建立一個新的 BrowserContext 以確保它們不會互相干擾。

Browser browser = playwright.chromium().launch();
BrowserContext context = browser.newContext();
Page page = context.newPage();
