Merhaba Arkadaşlar,
Bu yazımda selenium WebDriver daki JavaScriptExecutor kullanımından bahsedeceğim. JavaScriptExecutor, selenium ile JavaScript çalıştırmaya yardımcı olan bir class dır. JavaScriptExecutor, seçilen pencerede veya geçerli sayfada javascript’i çalıştırmak için “executescript” ve “executeAsyncScript” methodlar sunuyor.
JavaScriptExecutor ‘ ı neden kullanalım ?
Bazı projelerde eski teknolojiler kullanıldığından ötürü selenium ile bazı işlemleri yaptıramayabiliyoruz. Bu gibi durumlarda yapmak istediğimiz işlemleri javascript ile yapabiliriz ya da test süremizi daha da hızlandırmak için bazı işlemleri javascript ile yapabiliriz.
Şunları yapalım ;
Projemize öncelikle aşağıdaki ki interface imizi ekleyelim. Yazıyı hazırlamadan önce ben 26 method yazdım fakat javascript ile yapılacakların sınırı yok sizlerde kendi projenize ihtiyaca göre methodları ekleyebilirsiniz 🙂

import org.openqa.selenium.WebElement; public interface JSExecuter { <T> T executeScript(Class<T> clazz, String script, Object... args); Long getPageHeight(); String randomGenerate(int digit); Number randomNumberGenerate(int digit); String randomStringGenerate(int digit); JSExecuter openNewTab(String links); JSExecuter doubleClick(WebElement element); JSExecuter navigateToUrl(String links); JSExecuter click(WebElement element); String getText(WebElement element); JSExecuter selectByIndex(WebElement element, Integer index); JSExecuter selectByValue(WebElement element, String value); JSExecuter sendKeys(WebElement element, String value); Boolean isDisplayed(WebElement element); JSExecuter clear(WebElement element); String getSelectedOptionText(WebElement element); Long getSelectedOptionIndex(WebElement element); String getSelectedOptionValue(WebElement element); JSExecuter scrollToElement(WebElement element); Boolean isAttributePresent(WebElement element, String attribute); String getAttribute(WebElement element, String attribute); Boolean checkBoxChecked(WebElement element); JSExecuter allCheckBoxChecked(); JSExecuter pageZoom(Integer percentValue); JSExecuter pageRefresh(); String getCurrentUrl(); String getLocationPathName(); } |
Şimdi de methodların içeriğini doldurduğumuz class ımızı projemize ekleyelim.

Projemizin bir kenarında js katmanının olmasında fayda var 🙂
İyi Çalışmalar
