What are Hooks in Cucumber? || JUnit Cucumber Tutorial - Scenario Hooks
Cucumber supports hooks, which are blocks of code that run before or after each scenario. You can define them anywhere in your project or step definition layers, using the methods @Before and @After.
Cucumber Hooks allows us to better manage the code workflow and helps us to reduce the code redundancy. We can say that it is an unseen step, which allows us to perform our scenarios or tests.
Why Cucumber Hooks?
In the world of testing, you must have encountered the situations where you need to perform the prerequisite steps before testing any test scenario.
This prerequisite can be anything from:
Starting a webdriver
Setting up DB connections
Setting up test data
Setting up browser cookies
Navigating to certain page
or anything before the test
In the same way there are always after steps as well of the tests like:
Killing the webdriver
Closing DB connections
Clearing the test data
Clearing browser cookies
Logging out from the application
Printing reports or logs
Taking screenshots on error
or anything after the test
To handle these kind of situations, cucumber hooks are the best choice to use.
Unlike TestNG Annotaions, cucumber supports only two hooks (Before & After) which works at the start and the end of the test scenario. As the name suggests, @before hook gets executed well before any other test scenario, and @after hook gets executed after executing the scenario.

Feature: Thanks for all free tutorials Scenario: Thank you sir for another tutorial` Given user was afraid of bdd When with every tutorial user got better And user is more confident with bdd Then user is grateful

@vinithad1046 2 года назад

Thank You so much Naveen, I learned a lot from your videos, before i don’t know what is cucumber , my trainer taught in 20 min, i didn’t understand even a single bit, Now I understand more, thank you once again.

@VishalPatel-rg8xj Год назад

when you start explaining hooks I felt it will be confusing at large scale and you mentioned it in end...so satisfying

@HowTo-lc2rp 3 года назад

Lovely Explaination , Sir. In today's date I am thinking about becoming an automation tester , only because of your traning session , and nothing else. There is no other reason , believe me Sir. Other wise I was thinking about becoming a Busniess Analyst

@ramareddybheemanagoud2331 5 лет назад

@spiritualquest6092 3 года назад

Very good tutorials, thanks!

@naraharijagadish2586 5 лет назад

Hi naveen, I see that @After is getting executed before @After("@First") if u observe the result in console at the bottom. why is it happening?

@vimalmishra8693 6 лет назад

Hi Naveen , As i watched all the Cucumber BDD and it is very exceptional . I wanted to ask some things . as whole course is running one feature and one step definition at a time , would be very useful if you can add video which can run and support multiple feature file with multiple step definition , , i would like to add all common step definition in one class and then non common step definition in many separate classes . once again many thanks for your great support and invaluable knowledge.

@jayeshkumar2815 4 года назад

@kambalavijay6800 3 года назад

Thanks a lot the explanation, it made my life very easy after this. However I still have once question, what should be done for @BeforeAll and @AfterAll?

@aloneff7914 2 года назад

Thanks you so much...u r just amazing 🤩❤️

@MohanRaj-by9us 4 года назад

Thanks for the tutorial. I am the member of the channel for past 1 year and referring all your video tutorial, whenever, i am having doubts, I felt your tutorials are more informative and easily understandable to everyone. In my case, I wanted to capture the failure screenshot for each steps instead of every scenario. I saw that there is annotation @AfterStep & @BeforeStep is available in latest version of cucumber to perform step related actions. But, i will be not able to arrive and stuck with dependencies. Please help me to configure the same. Would be more helpful, if you share the POM.xml. Thank you Naveen.

@saipriya6603 6 лет назад

Hi Naveen, we have three test data in third scenario (with Examples)of hooks.feature, this means, i should get a total of five scenarios in console(one for deal,second for contact, three for last scenario which has Examples Test data

@vishwambharborde 6 лет назад

NO, hooks are not treaded as scenario, however if you have worked with testNG - before/after Hooks behave like BeforeMethod/afterMethod in testing, those are not printed in scenario list but console print will shows the execution steps of Hooks, so do in other report output format.

@nithinkumar492 5 лет назад

sir can u plz help with parallel execution in cucumber

@NikhilJain4 6 лет назад

Hi Naveen, why is "Global After" called before the "tagged after"?

@vishwambharborde 6 лет назад

we have to use the order in hooks, the order will execute incremental number for before and decremental in after

@mauryar16 5 лет назад

Thnx

@sunitasonavane1071 6 лет назад

Hi Naveen... thanks for series of BDD framework series . its really very helpful . Do you have any video or PPT stating how we need to go for Sprint automation in agile methodology... using junit test or API test or selenium webdriver test so that we can do high code coverage & regression and we can move towards zero defect in production also covered testing for all stories in sprint which further can be added in CI for future build so no manual regression required in future releases

@rizwan3564 Год назад

Hi Naveen, if i am having three steps which is already having step def implemented for each step Given step1 When step 2 Then step 3 Now i am creating 5 new scenario and i want the above three steps which is already implemented should run before executing my scenario. How can i achieve it? Note: I don't want to write above three steps again and again in my 5 scenarios. [This was asked in one interview]

@Bala-en5vb 6 лет назад

Great video

@syedshafiulla3093 4 года назад

Naveen , do we have any keyword in cucumber for executing test cases in sequential manner , like we have "Priority" keyword in TestNG?

@SuperSunilc 6 лет назад

Hi Naveen, thanks for another excellent series of BDD framework. What is the significance of runcukes in executing the BDD tests apart from these hooks concept?

@harithaatkuridevotional 4 года назад

Hi Naveen, I have a query, how can we exit cucumber test if a condition satisfies by skipping remaining steps of feature file?

@raisawate2812 4 года назад

Hello Naveen , How can i skip a single example from scenario outline examples Eg. Consider there 100 examples in Scenario outline i want to skip 99th Scenario outline example Please help me out with this query . Thanks for the support!!!

@amarmodi6442 4 года назад

I have observed one thing we are changing .feature path in TestRunner but step definition path is same i.e. whole folder name. Now my question is how mapping done internally for particular . feature file with same that step defination class file? As there are multiple steps definition files are there having some methods are common??

@RY-it6lm 6 лет назад

Naveen, all your videos show how to run a single feature file. I wonder why you never showed how to run multiple ones at the same time. I guess in that case, you would path it to the folder where you keep all the feature files but sometimes the ordering get confusing and I was hoping you would create a video regarding that.

@RajeevKumar-xd4gv 6 лет назад

Adam you can try with features= {"classpath:features"},

@RohitTyagiSironj 6 лет назад

@Naveen: Is there any video where I can see how to execute same feature file or scenario on multiple browsers in parallel?

@pasupuletibalaji4356 4 года назад

we will mention @Before and @After for every scenario in stepDef but I don't want to close my browser for every scenario. If I execute perticular single scenario need to login or else first time is enough and remaining test cases should execute . How to achieve this functionality?

@hondahnesscb3505 5 лет назад

Hello Naveen Sir, I have one doubt what if we used hooks and taga like(@smoke, @ regression etc) and in runner class with used tags{@smoke, @regression} will it ignore hooks like @After @first @Before etc? Please clarify this doubt

@bharathkoneru4008 4 года назад

In runner class, based on tags specified, respective scenarios will be executed, if the global & local hooks are defined, they will execute first(@Before)methods secondly scenario, then (@After) methods None of them will be ignored.

@priyasoni1019 6 лет назад

Hello Naveen, Why you commenting all other StepDefinition classes cant we give specific class path in glue=" ", i tried but its not working any other way is there? please let me know

@vishwambharborde 6 лет назад

we can you use tagged scenario to run in runner class. just have to ensure step def for scenarios are created one to one in entire project irrespective of which file feature or step-def is. meaning, here, Naveen is commenting (//) step-def methods because the same method definition already exist in other class -this block cucumber from compiling, due implementation duplicity...

@bharatkumar5277 6 лет назад

Hi Naveen, can you please clarify below usecase....I want to use the @Before and @ After only for the once..lets say there are 10 scenarios that needs to be executed but i want the @Before to be executed at the beginning of the scenario and @After at the end of all scenarios.Is this possible with hooks?

@Nutshell-Tech 6 лет назад

Though I didn't try, as today only I'm going through this video and I feel I can answer this. In featiure file please tag first scenario as @First and tag last scenario as @Last and in the hooks mention as @Before("@First") and @After("@Last") should solve your case.

@rajasekharmaddigalla1463 4 года назад

HI Naveen, Do we need to specify @Before and @After in each and every StepDefinition class (or) can't we declare it as globally (in base class)

@rohanchristopher2265 4 года назад

@after and @Before will not work inside the stepdefinition file it will give exception as "NosucchSessionException" so u need to create a seperate class for hooks and u need to only specify the hooks in that class

@rajasekharmaddigalla1463 4 года назад

@@rohanchristopher2265 Thank you for your replay,i tried by creating a separate hooks class,but it is coming up with multiple browsers , may i have your email id Rohan to share the code

@rohanchristopher2265 4 года назад

Okay did u keep u r kooks class in same package where step definition is there??

@rohanchristopher2265 4 года назад

Hooks*. rohanestar@gmail.com u can share

@test-ox1gi 3 года назад

Hello Naveen, Is there way how we can execute the feature files?

@rajasimhan9407 5 лет назад

Does before and after tags will run for all scenarios. What if I don't want a particular scenario not to have before and after execution and want other scenarios to use them in the same feature file For Instance If I have 10 scenarios in a feature I want the 8 to have before and after and any 2 without them How can we do this

@clloydwalton 5 лет назад

Add tags under before and after. This will solve your problem

@shanthikandasamy 4 года назад

Can any one tell whats the max no scenarions we can write in a single .feature file?

@shanthikandasamy 4 года назад

*Scenarios

@seshareddy7254 6 лет назад

What is meant by dry run and monochrome and Strict..

@jibolaolu 6 лет назад

Dry run is used to step defs with feature file making sure all steps covered while Strict is a way of making sure all methods are not empty, If Strict is set true and a method is empty it will return an error message, Monochrome is a way of structuring output in the console... i hope I've been able to answer the best way

Thank you very much friend..
