Selenium vs Cucumber: Core Differences

When liken testing tools,Cucumber and Seleniumoften come up together — but they serve rattling different use. Selenium is primarily abrowser automation framework, built for executing functional and regression tryout across multiple browsers and devices.

Cucumber, on the other hand, is abehavior-driven development (BDD) toolthat permit tests to be written in human-readable Gherkin syntax, making them accessible to business and non-technical stakeholders.

This comparability highlights howCucumber vs Selenium serve different rolesin test automation. Teams often combine them to balancetechnical mechanisation with business readability.

What is Selenium

is an mechanisation creature for. It helps in. Very clear, right? Or exactly a generic sentence that raises more enquiry than answers?

Let us appear at a scenario.

You develop a web application. Once you are done, you want to test it. So you will open it in Chrome. Click theMenuicon, and click around to ensure that everything is working as intended. But not everyone uses Chrome, and now you need to repeat everything in Safari and Firefox and every former browser and twist the exploiter uses. This is rather cumbersome. The load keeps increasing as you get deeper into the browser matrix.

Any small alteration that you create to your application also has to be tested on all these browser. Thus advertise any QA into the coney hole.

This is where Selenium comes to the rescue.

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

With Selenium, all that you have to do is write tests. These tests automatize the whole process for you. You can write tests for practically all the use instance like checking elements, functionality, behaviour, etc. Selenium executes these tests mechanically and in all the browsers you want.

Selenium back all major programming speech like JavaScript, Python, Java, PHP, etc. And when it comes to supported browsers, Selenium runs all the tests through the browser-specific driver. That means lead examination on the additional browser is just a matter of installing an additional driver.

BrowserStackallows you to seamlessly execute Selenium tests on different browsers. You can quiz your web applications on 3000+ real devices and get accurate results.

Advantages of Using Selenium

• Automates
• Open-source
• Supports multiple tabs
• Well documented
• Can be written in any popular programming lyric

Disadvantages of Using Selenium

• Requires browser-specific driver
• Doesn ’ t feature a built-in reporting tool
• It has challenges with deal iframes
• The user needs to be conversant with some scheduling language

What is Cucumber

Cucumber is the puppet for pen behaviour-driven tryout. But initiative, what are behaviour-driven tests?

You may know how to write general tests. Usually, it is something like, you find an element selector, use it check its contents, and compare it with the wait value. With you describe behavior. You compose human-readable schoolbook describe the user requirements. This text consequence in tests being executed. This is where Cucumber comes into play. This tool enables you to convert that text into the testing code. For instance, if there are multiple unit examination, with Cucumber you can describe some anticipate user behaviour. These tests often specify acceptance scenario for features.

When compose Cucumber tests, there are two component you want to do & # 8211; Steps and features.

1. Steps: Steps are functions. These role help you perform a examine action. That could be to load a web application, snap some element, enter schoolbook into the input battlefield, or anything that the user might be doing. These functions are written in the scheduling speech you chose and also contain text for which they are triggered.
2. Features: Features contain scenarios, which are your text. They describe behaviour begin with keywords and base on those sentences, Cucumber maps them to the right step to be executed.

It might be a bit simpler by habituate the model.

Scenario:The menu opens when the icon is tick
Givenyou charge the landing page
Whenyou click the menu detail
Thena menu will be visible

The above illustration has four line.

• 1st line: This is the scenario line and simply defines that it is the first of the test scenario. Something like a little description of what is happening in this trial.
• 2nd line: This first used step, and from the description of it, we can assume that the step code will open the landing page of the application in the browser.
• 3rd line: Once the page is loaded, this step will click on the menu item. The logic hindquarters would have a chooser for the menu icon on the page and induction a click yet on it.
• 4th line: This last line triggers step checking if the carte is visible. The way it is written supra is quite aboveboard and very understandable. However, in the step definition again, there would be some selector for the card element. Then the codification would try to bring that element and see if it exists and if it is seeable.

As you can see, tests written this way are easy to comprehend for both developer and business users. You might think, why would we want non-technical people to realize code? And that is a good question. But it is not about them understanding the codification, it is about getting both sides on the same conversation. Behavior-driven tests forthwith mirror requirements and could be used in your tag to delimit them.

Advantages of Using Cucumber

• It is human-readable, which signify job people can realise it
• Steps can be write in any programming language
• Because it uses human-readable text, can be used for line user requirements

Disadvantages of utilise Cucumber

• It requires user engagement to describe scenario right
• Requires maintenance of both step and scenario

Selenium vs Cucumber: Differences

Here are a few differences between Selenium and Cucumber:

1. Selenium is a test mechanisation framework whereas Cucumber is a behavioural testing puppet.
2. Selenium is written in program language like Java, .Net, etc. whereas Cucumber is publish both in programming words as well as field text.
3. Selenium supports conditional statements but Cucumber does not.
4. Test Scripts are written ground on requirements in Selenium but with Cucumber, you start with scenarios foremost.
5. are difficult to develop whereas Cucumber was easier to develop.
6. Identifying syntax errors is pretty easygoing while you are evolve the script, whereas you can not find errors in Cucumber.
7. Both Selenium supports Perl, Python, Java, PHP, .Net, etc.

Here is a tabular version of the differences between Cucumber and Selenium

When to use which?

From the description of what Selenium and Cucumber are it might be already clear. Both are used in testing, but each has a slightly different role., and Cucumber helps us do them more readable. You could think of it as motor a car or getting a taxi. Both will get you to your placement. You can use Cucumber without Selenium, just like you can use Selenium without Cucumber. But by using them together, you get a combination where you publish open and graspable tests to everyone with Selenium running them on all required browser. That said, you can use Selenium and Cucumber in tandem with each other.

Most organizations, today use Cucumber along with Selenium as it do it easier to say and see the flowing of applications among the members from different teams.

Cloud prove ware like BrowserStack support Selenium testing with Cucumber.
