Selenium and Capture Network Traffic

Had heard of it but never tried it my self till today, when a colleague asked about selenium being capable of recording http traffic or not.

Did a little Google and found that Selenium 1.0 has api - "captureNetweokTraffic" in DefaultSelenium class, and then needed to know how to use it. To be able to capture network traffic one should start selenium instance as -

selenium.start("captureNetworkTraffic=true");

and then launch the application usual way. Once you reach a point after which n/w traffic is to be captured then fire following method -


selenium.captureNetworkTraffic("xml");

We can pass - "xml", "plain" or "json" as parameter to this method. Since its return type is String, we can assert presence of any specific request on the response received

Though had some trouble while using captureNetworkTraffic, At times I would encounter Internal Server Error from selenium. Or then expected response string will not be available in String returned by captureNetworkTraffic, Though would always see same available from fire bug. But yet on the whole "captureNetworkTraffic" helped in achieving what I wanted to do.

How can you save resources when instantiaing driver?

I asked on my previous post about what was wrong in instantiating driver on set up method? And here is the solution video on my YouTube channel (After 5 years of gap I finally added new video tutorial :)) The solution described on video tutorial uses following set up - public class BaseClassOnDemandDriverSetup { private WebDriver driver ; @BeforeMethod public void setupTest () { // Any other set up goes here } @AfterMethod public void teardown () { if ( driver != null ) { driver .quit() ; } } public WebDriver getDriver () { if ( driver == null ) { WebDriverManager. chromedriver ().setup() ; driver = new ChromeDriver() ; } return driver ; } }

Security Testing and Selenium

I have come across many articles which talk of carrying out security testing with selenium however I found it very cumbersome to set up such tests. This is what this tutorial is going to make easy for you. It cover. My next Security Testing and Selenium YouTube video covers following - Importance of having security testing on CI What is dynamic application security testing Recommended tools from https://owasp.org/www-community/Vulnerability_Scanning_Tools What is https://owasp.org/ ?   Using https://www.zaproxy.org/    Project setup  <dependency> <groupId> org.zaproxy </groupId> <artifactId> zap-clientapi </artifactId> <version> 1.9.0 </version> </dependency> <dependency> <groupId> org.zaproxy </groupId> <artifactId> zap </artifactId> <version> 2.10.0 </version> </dependency> Start ZAP daemom (headless) mode  ./zap.sh -daemon -host 127.0.0.1 -port 8080 -config api.addrs.a

Using chrome console to test xPath and css selectors

Since the advent of selenium there have been many plugin to test xPath / css selectors but you don’t need any of them if you have chrome browser. Using Chrome console you can test both xPath and css selectors. Launch website to be tested in chrome browser and hit F-12 and you would see chrome console opened in lower pane of application - Hit escape key and console would open another pane to write element locators - And now you can start writing xPath or css selectors in chrome console and test them - The syntax for writing css id - $$(“ ”) And hit the enter key. If your expression is right then html snippet of the application element corresponding to the css selector would be displayed - If you mouse over the html snippet in chrome console then it would highlight the corresponding element in application - If you want to clean console of previously written element selectors then just hit ctrl+L keys and chrome console would be empty again.
