Take Screenshot in Appium with this Simple Code

Screenshots serves an important role of acting as an evidence of any tests performed. Therefore screenshot capture functionality is very useful in any automated testing activities. WebDriver provides TakeScreenshot interface to capture screenshot of a web page. We can leverage that same method to take screenshot in Appium tool as well. In this post, we will explore how we can capture screenshot of an Android app using Appium tool.

For our example, we will capture screenshot of a native Android app running on Android emulator. We hope you have already setup Appium to use with an Android app. The code that we will see in steps below is written in Java. OK, enough with the talks. Let’s delve deep into the actual implementation now.

We will be using Augmenter class of WebDriver for screenshot capture functionality (Therefore, please make sure you have imported org.openqa.selenium.remote.Augmenter class in your test). To take screenshot in Appium, you just have to use below code in your tests.

WebDriver driver1 = new Augmenter().augment(driver);

File file  = ((TakesScreenshot)driver1).getScreenshotAs(OutputType.FILE);

FileUtils.copyFile(file, new File("Screenshot.jpg"));

As you can derive, the code uses the same method as WebDriver to take screenshot in Appium but with an additional help of Augmenter class.

On running this code, you will find a Screenshot.jpg file in root folder of your WebDriver project. You can also specify directory of your choice as copyFile method’s parameter.

The example code we have shown above is tested on Android app. But as Appium has a flexibility to use same code for both iOS and Android apps, you should be able to use same code on iOS app as well.

We hope the above tip to capture screenshot in Appium tool is useful to you. Let us know if you run across any issue while getting this to work. We would love to have your feedback in comments.

JMeter Exceeded Maximum Number of Redirects Error Solution

While running performance test, JMeter allows maximum 5 redirects by default. However, if your system demands more than 5 redirects, it may result in JMeter exceeded maximum number of redirects error. In this post, we have listed down steps to overcome this error. Actual error in JMeter: Response code: “Non HTTP response code: java.io.IOException” Response message: “Non HTTP response message: Exceeded maximum number of redirects: 5” This error is noticed because JMeter allows maximum 5 redirects by default and your system may be using more than 5 redirects. You need to increase this count to more than 5 in jmeter.properties file. Follow below steps to achieve this. Navigate to /bin directory of your JMeter installation. Locate jmeter.properties file and open it in any editor. Search for “httpsampler.max_redirects” property in opened file. Uncomment the above property by removing # before it. Change to value to more than 5 Eg. 20. Save the file and restart JMeter. If

SSO with SAML login scenario in JMeter

SAML(Security Assertion Markup Language) is increasingly being used to perform single sign-on(SSO) operations. As WikiPedia puts it, SAML is an XML-based open standard data format for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. With the rise in use of SAML in web applications, we may need to handle this in JMeter. This step-by-step tutorial shows SAML JMeter scenario to perform login operation. First request from JMeter is a GET request to fetch Login page. We need to fetch two values ‘SAMLRequest’ and ‘RelayState’ from the Login page response data. We can do this by using Regular Expression Extractor . These two values need to be sent in POST request to service provider. Refer below image to see how to do this. We will get an HTML login page as a response to the request sent in 1st step. We need to fetch values of some hidden elements to pass it in the next request. We can do this b

A Tutorial to Send Email using JMeter

Sending email is a mundane activity in any professional’s life. It’s a common medium for communication nowadays. Therefore performance testing of email server is not only important but necessary for an organization. JMeter can be helpful to perform load testing in such scenarios. In this tutorial, we will see how JMeter can be used to send email. We will use SMTP Sampler of JMeter to send an email. JavaMail API is needed to enable email functionality in JMeter. Download it from here and paste the jar in JMeter’s lib folder. Now, perform below steps to configure SMTP Sampler. Add a new Thread Group under Test Plan. Right click on Thread Group and select Add–>Sampler–>SMTP Sampler. We need to populate SMTP server’s details in this sampler. We will use GMail for sending an email. For this, enter these values in SMTP Sampler fields. Server: smtp.googlemail.com, Port: 587. Provide values in Email Address From and To fields of Mail Settings section to specify sender and reci
