Postman POST request allows appending data to the endpoint. This is a method used to add information within the request body in the server. It is commonly utilized for passing delicate information.Once we send the request body via the POST method, the API, in turn, yields certain information to us in Response. Thus a POST request is always accompanied by a body in a proper format.Create a POST RequestStep1 − Click on the New menu from the Postman application. The Create New pop-up comes up. Then click on the Request link.Step2 − SAVE REQUEST pop-up comes up. Enter Request name ... Read More
Postman DELETE request deletes a resource already present in the server. The DELETE method sends a request to the server for deleting the request mentioned in the endpoint. Thus it is capable of updating data on the server.Before creating a DELETE request, we shall first send a GET request to the server on the endpoint http://dummy.restapiexample.com/api/v1/employees .On applying the GET method, the below Response Body is obtained.Let us delete the record of id 2 from the server.Create a DELETE RequestStep 1 − Click on the New menu from the Postman application. The Create New pop-up comes up. Then click on ... Read More
We can parameterize Postman requests to execute the same request with various sets of data. This is done with the help of variables along with parameters. A parameter is a part of the URL used to pass more information to the server.The data can be used in the form of a data file or an Environment variable. Parameterization is an important feature of Postman and helps to eliminate redundant tests. Parameters are enclosed in double curly braces {{parameter}}.Let us take an example of an URL:https://www.tutorialspoint.com/index.htm. We shall create a variable as URL then use it for parameterization of the request. ... Read More
A session is a temporary fold that stores values of variables. They are used for the present instance and have a local scope. In Postman, we can modify the session variable value to share workspace among teams.Postman gives the feature of local session share. Even if a Collection can be shared among teams, the sessions are never shared. Different tokens have to be generated while a task is to be carried out in a team structure.A session has a local scope for a user within his Workspace and any modifications he makes shall not be reflected in the server. In ... Read More
Scenario Outline is used to replicate the same Scenario with a different data set. Writing the same tests with different values is cumbersome and time taking. For instance, We can club the above two scenarios with the Scenario Outline.Thus, we see that a Scenario Outline should be accompanied by keyword Examples. A Scenario Outline is executed once for each of the rows appearing below the Examples segment.Also, we have seen that the Given step has the delimiter. It points to the header of the Examples table. SpecFlow shall put the values within this table before the task of matching ... Read More
We can perform data-driven testing with the help of keyword Examples. We shall also take the help of keyword Scenario Outline to execute the same Scenario over multiple values.The data sets to be taken into consideration shall be passed below the Examples section one after another separated by | symbol. So, if there are three rows, we shall have three test cases executed from a Single scenario.Also, the Given step has the delimiter. It points to the header of the Examples table. SpecFlow shall put the values within this table prior to the task of matching a step with ... Read More
The Background keyword is applied to replicate the same steps before all Scenarios within a Feature File.Background RulesLet us describe some of the rules while applying Background −It should be used for defining simple steps unless we are forced to bring the application to a state which requires complicated steps to be carried out. As requested by the stakeholders of the project.It should be brief and realistic.All the Scenarios should also be short and to the point.Background ExampleLet us see an example where we have used Background steps to be executed before all the tests in the Feature File.
