This feature file contains two scenarios where only one has been marked as SmokeTest tag. It is annotated with @RunWith(Cucumber.class). This calls the need of an intermediate – Step Definition file. So that we can witness how the pass and failed report looks like. Then hover over Run As option then clicks on Cucumber Feature. Why we need − Maven is a build automation tool used primarily for Java projects. Right-click and select the option ‘Run as’, You will observe the following things when you run this class file −. It gets downloaded along with the other Cucumber jars. Apart from that, it has many other options for customization, reporting, selective execution, etc. Comment is basically a piece of code meant for documentation purpose and not for execution. It looks simple when we just have one, two, or maybe five scenarios in a feature file. Provide group Id (group Id will identify your project uniquely across all projects). That said, we will need people from different community like developers, project managers, product owners, and testers while developing test scripts. In this example, the steps in red indicate a failure, while the step in blue indicates that the step was not run due to the failure of the previous steps. When the user clicks on Help, then the Help page opens. This has become the reason for Cucumber's popularity over other frameworks, like JBehave, JDave, Easyb, etc. Following are a few tips and tricks, which makes Cucumber debugging a bit easy. Scenario outline is similar to scenario structure; the only difference is the provision of multiple inputs. Runner File: This is just to execute the actual test script written over the Stepdef file by referring to the feature file. There does exist a Grunt plugin for executing Cucumber.js tests. So with each function, whatever code you want to execute with each test step (i.e. Cucumber is a testing tool that supports Behavior Driven Development (BDD). Write the following text within the file and save it. The user should be navigated to the home page if the username and the password are correct. You will observe the following things when you run this class file. hooks.js Step 12 Run Cucumber Run Cucumber: Test Automation using Cucumber … The user should be shown an error message when the username and the password are incorrect. JSON reports bring a different value to the table. Step 6 − Create step definition file (to be covered later). The scenario will get executed as many times as the number of inputs provided. There is no ground rule in Cucumber about names. Create a Maven Test Project named as AnnotationTest. It... http://career.guru99.com/category/career-guide/, You need 2 Files – Features and Step Definition to execute a Cucmber test scenario, Features file contain high level description of the. Defining logical or in runner class − [@dev,~@wip] − It says that scenarios matching both these tag needs to be executed. Also the html report generation can be configured here. Features file contain high level description of the Test Scenario in simple language. Cucumber-JVM natively supports parallel test execution across multiple threads. Why we need − Maven is a build automation tool used primarily for Java projects. Create a step definition file (to be covered later). Below snapshot shows the output of the program. Create a runner class named as runTest.java inside the package. A Feature can be defined as a standalone unit or functionality of a project. (
). It has been imported in POM project file with cucumber-junit. Next, install the gems you need for Cucumber web testing. There is one more way through which we can run the Cucumber test that is through command line interface. Typically, what can be the input parameters while registering a new user for a social networking site? * AND keyword is used to show conjunction between two conditions. Step 4 − Set the environment variable as shown in the following screenshots. Running Our First Cucumber.js Test Script The next step in this Cucumber.js tutorial is to execute a sample application. Test scenario will be executed for each of the input provided. Code gets freezed only after successful execution of defined test scripts. Alternatively, we could use Maven Surefire. Both the scenario will get executed one by one. Therefore we need to first configure running the project in order to generate json log data files. Feature − User login on social networking site. If it does not happen, code refactoring will be needed. Stakeholders write down the feature file. Step 3 − Add dependency for selenium: This will indicate Maven which Selenium jar files are to be downloaded from the central repository to the local repository. The last goal in this tutorial is to be able to generate a cucumber report. Step 11 − Create a package under src/test/java named as cucumberJava. In order to achieve this, we need to integrate Cucumber with other open source tool like Ant/Junit. The answer is, Behavior Driven Development (BDD) Framework. The highlighted text in the program refer to the comments in the code. This was the evolution point for Gherkins. Let’s automate a scenario in order to understand annotations better. Download Eclipse from https://eclipse.org/downloads/, Download Maven −https://maven.apache.org/download.cgi. So far we have seen how to run a test using Eclipse IDE. We can say that it is an unseen step, which allows us to perform our scenarios or tests. Run the test using option − Select runTest.java file from package explorer. (
). To install Cucumber, first update the current gem setup. OR can be used in conjunction with GIVEN, WHEN and THEN statement. Step 2 − Create a package named dataTable under src/test/java. The report will be there named as cucumber.json (as provided in … You can choose any name which is in lowercase). Test Runner - CucumberTestSuite . Now, suppose we want to check if login is successful for all three possible types of inputs, which are username, email address, or phone number. We cannot run a Feature file by its own in cucumber based framework. 1. Create environment variable MAVEN_HOME as shown in the following screenshot. The excel can be utilized to execute different types of test cases using various type of test data. You will see the report mentioned in the following screenshot after placing line breaks −. AND can be used with any other keywords like GIVEN, WHEN and THEN. Feature File is a starting point of the Cucumber test because it serves as an automation test script and the living documentation. Cucumber reports plugin to generate readable reports So in the beginning, developers, project managers, QAs, user acceptance testers and the product owner (stockholder), all get together and brainstorm about which test scenarios should be passed in order to call this software/application successful. You will be able to see a Maven repository like shown in the following screenshot. Cucumber doesn’t really know which piece of code is to be executed for any specific scenario outlined in a feature file. Run as JUnit. The program will start running. By now we have seen how easy HTML report is. At the bottom we have provided multiple input values for the variables “Username” and “Password”. It will build the test report in the specified format (which can be html/JSON). The previous command runs everything as mentioned in the JUnit Runner class. Given I am on the new user registration page, Then the user registration should be unsuccessful. This file will basically instruct cucumber that we are going to use Chrome. And lastly, let’s explore an example how it all stacks up. Each feature can have one or more scenarios and every scenario consists of one or more steps. Step 1 − Download jdk and jre from the following link http://www.oracle.com/technetwork/java/javase/downloads/index.html. After that you will be able to see a Maven repository like the following screenshot. Feature File consist of following components - Feature: A feature would describe the current test script … Create a feature file, named as dataTable.feature inside the package dataTable (see section scenario outline for more detailed steps). This will fulfill the need of a good documentation as well. TestRunner class is created under src/ test/java. This is where all of your cucumber features will reside. Cucumber supports running tests with JUnit and TestNG. Step 6: Replace all the Throws exception with the required code, which will be executed when the test case is run. Edit Path variable and include Maven as shown in the following screenshot. Background generally has the instruction on what to setup before each scenario runs. This is how you need to write all the files and execute the program. When I enter Username as "" and Password as "". Step 3) Select the Project location and click "Create." Server Directory − Also we have a provision to specify a target directory as any directory on the server, which is publically accessible. However, if we want to override the configurations mentioned in the Runner, following are the few examples to do it. npm run test. Let’s continue with the same example of Facebook login feature. So, in the given example, test scenario will be executed three times. Click on Finish. Then holds the expected result for the test to be executed. Running any test framework from the Terminal has its own advantages, such as overriding the run configurations mentioned in the code. It’s a good idea to use a name similar to the file name. Let’s review some important best practices needed before you start developing Cucumber tests. All the words highlighted in bold are Gherkin keywords. Hence, while we are automating our test scenario with Cucumber, it is essential to know, how better we can generate our Cucumber test reports. Go to Project → Clean − It will take a few minutes. Method/function/piece of code, defined within Before and After hooks, always run, even if the scenario gets passed or failed. Give the file a name such as cucumberJava.feature. There is no limit in defining tags within the feature file. Later, in the runner file, we can decide which specific tag (and so as the scenario(s)) we want Cucumber to execute. We need to create a Java class which will run the Feature File. If you want to know more about this library, please refer to the introduction to WireMock. Given − Prerequisite before the test steps get executed. Finally, at the bottom you will find the following information. So, it is important to use/put comments at appropriate places in the file. Example − THEN login should be successful. Feature File consist of following components - Feature: A feature would describe the current test script … The file, in which Cucumber tests are written, is known as feature files. It exactly highlights the color of failed scenario. Feature − Login functionality for a social networking site. Let’s think of some more possibility. To have an organized structure, each feature should have one feature file. So this is ideal to be used for code when we want to set up the web-browser or we want to establish the database connectivity. Now go to your Cucumber feature file and do a right click. Right click and select option Run as. Consider that out of 25 defined scenarios, 10 are marked as smoke test. JUnit acts as a bridge between these two. Then − What should happen if the condition mentioned in WHEN is satisfied. Tag starts with “@”. As far as possible, keep each step completely independent. While working on automation, we may face variety of scenarios. Sharing photos or videos on the social networking site. The user should be navigated to home page, if the username and password are correct. Open cucumber.json file with the text editor. Step 7 − Create Junit runner to run the test (to be covered later). Create environment variable MAVEN_HOME as shown in the following image. It is important to understand what Junit is, before we begin our discussion for Cucumber JUnit Runner. Inside the dependencies tag, create dependency tag. The user should be able to login into the social networking site if the username and the password are correct. In this tutorial, we will create Cucumber Scripts to test two scenarios Cucumber Script 1:... Training Summary Behavior Driven Development (BDD) is a rising methodology to test and check your... Cucumber installation could be tiresome but its relatively easy. The user should be able to login with correct username and correct password. It provides the logical AND condition between any two statements. Gherkin is a plain English text language . To be more precise, Cucumber can be defined as a testing framework, driven by plain English text. Step 1− Create a Maven Test Project named commandLine. Identifying the cause of failure and correcting it is very important. This can be divided into two steps, Annotation is a predefined text, which holds a specific meaning. The TestRunner.java file is executed as a jUnit Test. Example @Dev,@Ignore. Add dependency for Cucumber-JUnit: This will indicate Maven, which Cucumber JUnit files are to be downloaded from the central repository to the local repository. A file in which we store features, description about the features and scenarios to be tested is known as Feature File. The very basic form of the file is an empty class with @RunWith(Cucumber.class) annotation. It generates the report in the same way as it is a feature file, so tracing is also made easy. You may observe the following things upon successful execution. It executes the test scripts, which have been defined in the feature file (to be covered in subsequent chapters). If you use triggers for the project, don’t worry, test run will start with your default parameters automatically. For this, Cucumber has already provided a way to organize your scenario execution by using tags in feature file. Then, login should be unsuccessful. On one hand, Cucumber is providing a way for non-technical person to define test cases for a product, and on the other hand, our expectation is for smooth and timely execution of such test cases. Do not repeat the test scenario, if needed use scenario outline to implement repetition. Gherkin is a plain English text language . It recognizes the feature files present by the extension as login.feature; It executes the step_definition files, by reading the Given, When & Then statements, by matching using RegEx from the Feature files; The tests are executed using a headless browser - PhantomJS. It which executes the steps on Application Under Test and checks the outcomes against expected results. The user should not be able to login with correct username and incorrect password. 3)Easy to Use-One-Click: As the framework can be triggered on single click, it makes it easy for anyone to execute the test and study the response through reports. JSON-Java script object notation is another format for generating Cucumber test reports. It is a very simple notion, but what we need in order to get this concept implemented. In nutshell, when scenario does not change but only the data value gets changed, it is advisable to use scenario outline data tables. Cucumber supports over a dozen different software platforms like −. How does the feature of this product/project look like? Create a JUnit runner to run the test (to be covered later). We need to create a Java class which will run the Feature File. This file will basically instruct cucumber that we are going to use Chrome. The code has to pass the test scripts defined in BDD. An example of a step definitions file for Rational Functional TesterCucumber It has been imported in POM project file with cucumber-junit. Gherkin will parse each step written in step definition file (to be covered later). Click BUILD to start test run. For a step definition to be executed, it must match the given component in a feature. When − Specific condition which should match in order to execute the next step. Here, we will take examples of JUnit further because, it provides support for Java language. This report is generated based on Cucumber builtin json … There will be times where you try to click on something, for example, and it’s not there. Step 3 − Install Cucumber and other Ruby gem. Step 5: Create a FirstStep.java file in package StepDefinitions. So, it is actually not relevant to the essence of “Given statement”, and it is more like a setup for the test. It allows the test script to be written without knowledge of any code, it allows the involvement of non-programmers as well. Cucumber hook allows us to better manage the code workflow and helps us to reduce the code redundancy. Debugging option is available with Eclipse. Tag can also be defined at a feature level. Go to the package explorer on the left hand side of Eclipse. There does exist a Grunt plugin for executing Cucumber.js tests. It contains a base workspace and an extensible plug-in system for customizing the environment. We will see more about feature files in the following chapter. It can be development prospective, business prospective, etc. JUnit runs the feature files in parallel rather than scenarios, which means all the scenarios in a feature file will be executed by the same thread. Right-click and select the option ‘Run as’. Let’s take a very common example of a social networking site. Finish the installation and open the IDE. Step 2 − Unzip the file and remember the location.
