Automating Complex Course Creation with Selenium Java: A Full Code Walkthrough

The author shares a comprehensive Selenium‑Java automation script used to create both formal and live courses on an education platform, illustrating how to handle a variety of UI interactions such as selecting grades, subjects, teachers, dates, times, and uploading media.

Creating a Formal Course

public static void createFormalCourseAndSale(WebDriver driver, String grade, String subject) throws InterruptedException {
    clickCourse(driver);
    clickFormalCourse(driver);
    clickAddCourse(driver);
    findElementByIdAndClearSendkeys(driver, "input-title", "测试班课"+grade+subject); // input course title
    findElementByIdAndClick(driver, "button-toggle-grade"); // select grade
    findElementByTextAndClick(driver, grade);
    findElementByIdAndClick(driver, "button-toggle-subject"); // select subject
    findElementByTextAndClick(driver, subject);
    findElementByIdAndClearSendkeys(driver, "input-description", "测试招生人数1人"); // input description
    findElementByIdAndClick(driver, "button-toggle-teacher_id"); // select main teacher
    findElementByTextAndClick(driver, "李");
    // ... (additional field inputs omitted for brevity) ...
    findElementByIdAndClick(driver, "button-toggle-live_address_id"); // select live room
    findElementByXpath(driver, ".//*[@id='dropdown-live_address_id']/li["+getRandomInt(5)+"]/a"); // random live room to avoid conflict
    // Save and confirm
    clickSave(driver);
    boolean key1 = true;
    while(key1){
        if (exists(driver, By.xpath("html/body/div[12]/h2")) & getTextByXpath(driver, "html/body/div[12]/h2").equals("保存成功")) {
            key1 = false;
            break;
        }
    }
    clickSure(driver);
}

The script uses helper methods like clickCourse, findElementByIdAndClick, and findElementByTextAndClick to interact with the page, and it inserts static values for fields such as price, enrollment limit, and video URLs.

Creating a Live Course

// After confirming the formal course is saved, the script proceeds to create a live session
findElementByIdAndClearSendkeys(driver, "input-title", "直播课1"); // live course name
findElementByIdAndClick(driver, "input-begin_time_date"); // start date
findElementByTextAndClick(driver, "30");
findElementByIdAndClick(driver, "input-begin_time_time"); // start time
// Select specific start and end times via XPath
findElementByXpathAndClick(driver, "html/body/div[3]/div[3]/div/div[2]/div[2]"); // 1:00 start
findElementByXpathAndClick(driver, "html/body/div[3]/div[3]/div/div[3]/div[1]"); // end time selection
// Set deadlines for exercises and revisions, upload cover image, etc.
// Save and verify success using the same boolean‑loop pattern as above

A critical note highlighted by the author is that the conditional check must use the single ampersand ( &) instead of the logical AND ( &&); using && would cause a runtime error in this context.

Verification Loops

boolean key2 = true;
while(key2){ // wait for save confirmation
    if (exists(driver, By.xpath("html/body/div[8]/h2")) & getTextByXpath(driver, "html/body/div[8]/h2").equals("保存成功")) {
        key2 = false;
        break;
    }
}

Both loops rely on the presence of a specific heading element and the exact text "保存成功" ("Save Successful") to determine when the operation has completed.
