Why choose Cypress?

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…

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…

How to make an architecture roadmap plan?

How to make an architecture roadmap plan?

Comments 0 Comment

Some time ago in my current company, we faced a challenge of preparing the long term architecture roadmap. Strategic planning is a very important part of architect work. We need to know what our destination is before we start a journey. That’s why all the technical work needs to be aligned with a big picture of the technical organization. It is worth to do this at least once a year to keep all the technical goals clear and updated with…

Secure way to create change email process

Secure way to create change email process

Some time ago I faced a challenge to design secure method for change email process in our authentication service. Every system has an user and usually uses the email address as a login to the systems. Moreover, they use email address for the purpose of communication with the end user. Even if we had an artificial login name in system, we should still care about the way, how we communicate with the user. Additionally systems use email address for forget…

Obowiązki architekta IT

Obowiązki architekta IT

Co jakiś czas ktoś zadaje mi pytanie: czym właściwie zajmuje się w pracy? Pomyślałem więc, że wartościowe będzie opisanie tutaj, czym właściwie zajmuje się architekt IT.Często ta rola kojarzona jest z dość zamkniętym kręgiem wszystkowiedzących osób, które za zamkniętymi drzwiami podejmują wszystkie “ważne” decyzje w projekcie. Znam też historie architektów, którzy autorytarnie podejmowali decyzje, które nie zawsze wychodziły na zdrowie zespołowi. Myślę, że pojęcie architekta jest dość pojemne i każdy może o tej funkcji myśleć w inny sposób. Postaram Ci się…

Niedawno dopadło mnie pewne poruszające uczucie, które nawet mnie samego zaskoczyło.Upłynęło już dużo czasu od mojego ostatniego wpisu na bloga. Patrząc na ostatni wpis – aż 2 lata. Potrzebowałem tej przerwy w momencie, gdy przestałem widzieć większy sens w tym, co robię. Spojrzenie wstecz Czas ten był dla mnie bardzo owocny. Zarówno w sferze prywatnej jak i zawodowej. Prywatnie zostałem ojcem, co niesamowicie poszerzyło moje horyzonty, kompletnie zmieniło zwyczajny dzień i nieustannie wymaga coraz lepszej organizacji, aby nadal mieć czas…

Testing the same behaviour every time

Testing the same behaviour every time

Comments 1 comment

Tests give us an assurance which application works fine. We usually want to execute them on some Continuous Integration servers. It is very convenient because we can configure them to run after each repository commit or once a day.

Continuous integration flow usually works as follows. The application is built on CI server and then it executes all tests. Because all tests run on the same database, it is hard to make all them all independent. However, test independence is a very important principle. The result of one test may affect the correctness of another test. It is especially problematic if we want to run tests in parallel. We can’t be sure what will be the order of execution. It is not only the problem of the database. The browser can also store a state of the application.

What is a Test Case? What does it include?

A Test Case is a step by step description of the testing process and a set of conditions under which a tester can determine if the application works as expected.

It includes:
– test case description
– test steps
– requirements
– expected result

Sometimes we need to create a system exposed to a public web application. We may even need to create it for the broad group of customers. In that case, we need to develop it working on many different types of browser versions. In usual development, we would be forced to open the website in each browser ant test in manually. It would be very beneficial if we can automate it.

We can perform testing on multiple browsers very simple using Selenium WebDriver. We will just use its ability to works with different drivers and configure them.
