JSON (JavaScript Object Notation) is an open text format consisting of attribute–value pairs.Although JSON is derived from the JavaScript scripting language, it is a language-independent data format.JSON is commonly used for data transmissions between a server and web application, like AJAX and all kindof Web services.Use JSONBuddy as your JSON editor for Windows PCs to create and modify JSON content or JSON Schemafiles and get access to extraordinary editor features like JSON well-formed checking, intelligent auto-completion,pretty-print, remove whitespace and JSON validation. JSONBuddy also providesadditional functionalities to work efficiently with JSON:. Convert between XML and JSON. Convert JSON to CSV text. Import CSV and get XML or JSON data. Apply stylesheets to JSON and generate HTML. JSON Pointer evaluation.
JSONBuddy has a built-in powerful Grid style editor for JSON. This new editor view simplifies the creationand editing of JSON text even more and guarantees that any JSON content is well-formed and ready to be parsed.A grid style editor gives additional overview of the JSON content and allows quick collapsing and expandingto set the focus on the JSON parts you are currently interested in. By using a grid style editor, even userswho are not familiar with the JSON format are enabled to create and edit complex JSON content.
Json Grid Viewer converts these array of object into friendly table format. What is GridSync feature. When user clicks on any of the Grid element, say table cell, column or row, the left Json panel navigates to the associated Json field, providing instant preview of actual data. Convert JSON to HTML Table. Use this tool to convert JSON into an HTML Table. See also Convert HTML Table to JSON Step 1: Select your input.
What is Selenium Grid?Selenium Grid is a part of the Selenium Suite that specializes in running multiple tests across different browsers, operating systems, and machines in parallel.Selenium Grid has 2 versions - the older Grid 1 and the newer Grid 2. We will only focus on Grid 2 because Grid 1 is gradually being deprecated by the Selenium Team.Selenium Grid uses a hub-node concept where you only run the test on a single machine called a hub, but the execution will be done by different machines called nodes.
In this tutorial, you will learn-.When to Use Selenium Grid?You should use Selenium Grid when you want to do either one or both of following:. Run your tests against different browsers, operating systems, and machines all at the same time. This will ensure that the application you areis fully compatible with a wide range of browser-O.S combinations. Save time in the execution of your test suites.
If you set up Selenium Grid to run, say, 4 tests at a time, then you would be able to finish the whole suite around 4 times faster. Grid 1.0 Vs Grid 2.0Following are the main differences between Selenium Grid 1 and 2.Grid 1Grid 2Selenium Grid 1 has its own remote control that is different from the Selenium RC server.
They are two different programs.Selenium Grid 2 is now bundled with the Selenium Server jar fileYou need to install and configureAnt first before you can use Grid 1.You do not need to install Apache Ant in Grid 2.Can only support Selenium RC commands/scripts.Can support both Selenium RC and WebDriver scripts.You can only automate one browser per remote control.One remote control can automate up to 5 browsers.Selenium Grid ArchitectureSelenium Grid has a Hub and Node Architecture. How to Set Up Selenium Grid?
Using Command LineIn this section, you will use 2 machines. The first machine will be the system that will run the hub while the other machine will run a node. For simplicity, let us call the machine where the hub runs as 'Machine A' while the machine where the node runs will be 'Machine B.' It is also important to note their IP addresses. Let us say that Machine A has an IP address of 192.168.1.3 while Machine B has an IP of 192.168.1.4.Step 1Download the Selenium Server from.Step 2You can place the Selenium Server.jar file anywhere in your HardDrive.
But for the purpose of this tutorial, place it on the C drive of both Machine A and Machine B. After doing this, you are now done installing Selenium Grid. The following steps will launch the hub and the node.Step 3. We are now going to launch a hub.
Go to Machine A. Using the command prompt, navigate to the root of Machine A's - C drive, because that is the directory where we placed the Selenium Server. On the command prompt, type java -jar selenium-server-standalone-2.30.0.jar -role hub. The hub should successfully be launched. Your command prompt should look similar to the image belowStep 4Another way to verify whether the hub is running is by using a browser. Selenium Grid, by default, uses Machine A's port 4444 for its web interface.
Simply open up a browser and go toAlso, you can check if Machine B can access the hub's web interface by launching a browser there and going to where 'iporhostnameofmachineA' should be the IP address or the hostname of the machine where the hub is running. Since Machine A's IP address is 192.168.1.3, then on the browser on Machine B you should typeStep 5.
Now that the hub is already set up, we are going to launch a node. Go to Machine B and launch a command prompt there. Navigate to the root of Drive C and type the code below. We used the IP address 192.168.1.3 because that is where the hub is running.
We also used port 5566 though you may choose any free port number you desire. NOTE: You now have to give path to the Gecko driver if using Firefox. Here is updated code that needs to be usedjava -Dwebdriver.gecko.driver='C:geckodriver.exe' -jar selenium-server-standalone-3.4.0.jar -role webdriver -hub -port 5566.
When you press Enter, your command prompt should be similar to the image below.Step 6Go to the Selenium Grid web interface and refresh the page. You should see something like this.At this point, you have already configured a simple grid. You are now ready to run a test remotely on Machine B. Running a Sample Test Case on the GridBelow is a simple WebDrivercode that you can create in Eclipse on Machine A. Once you run it, automation will be performed on Machine B.The test should pass.Selenium grid configuration using JSON File:JSON stands for Javascript Object Notation.
It is a standard format used for interchange of data between browser and the web server. Selenium has an in built JSON config file that can be used to set up selenium grid.Below are the steps to configure selenium grid using JSON config file.Step 1) Download the code for JSON config file using the below path.
