This article shows you the differences between Selenium library and Cypress framework. Cypress is a modern end to end testing library – a competitor of Selenium. I recommend you to get familiar with the general description of Cypress and description of Selenium problems. I wrote about it earlier (http://www.diwebsity.com/2019/07/16/why-choose-cypress/).  Below is a table with a comparison between these two approaches (libraries) line by line for each category. I tried to be as objective as possible. This table is intended to…

What is it? Cypress (https://www.cypress.io/) is a quite new testing framework. It becomes very popular last year. Mostly among the front-end developers. It is not surprising when we look into the most interesting features of this library: Modern UI with the ability to: preview test execution, time travel in test execution, validate and debug the page during the testing. The integrated mechanism for network call simulations. All in one solution. The new kind of UI is especially interesting because it…

Selenium library is a very popular standard. It has many advantages, but it also has many problems. In this article, I want to list all Selenium problems and try to address them one by one. At first, we need to define, what are the most important problems: Hard to select elements on the web page This problem is not related strictly with the Selenium library. It is related mostly with a poor semantic description of the element on the application…

Some times ago I faced the problem with the low quality of the customer’s demonstration. When we try to present our application for the wider audience, we have problems with doing some basic scenarios again and again. We thought that we well tested this functionality. We were using it every day, and everybody in our team was checking it after each change. However, the application functionality still evolving. Moreover, any modification of the code may result in changing final functionality. Because of many changes before demo we can’t test it enough to be 100% sure that everything works fine.

During the API creating work, it is necessary to test API calls. We can do this in many ways. One of the good method could be just using browser to enter url in address bar. However using this method we can test only GET requests. Also there is problems with setting up headers.

Other method to test HTTP requests is using cURL format and appropriate software. This is a console program, so it is very extensible and powerful. However it is a console program and it is more complicated to use and we should manage request database on our own. It can be easier.

Fortunately it exists a program Postman. It is a software for all kind of HTTP request work. It can be installed as a standalone application and as a Chrome plug in.
