Behave – Hooks

Behave - Hooks

Behave Hooks setup and teardown functions are implemented in a file called the environment.py which is within the same directory that contains the steps folder. The connection, configurations, and so on.

The environment.py functions −

  • before_feature(context, feature) − Executes prior every feature.
  • before_scenario(context, scenario) − Executes prior every scenario.
  • before_step(context, step) − Executes prior every step.
  • before_tag(context, tag) − Executes prior every tag.
  • before_all(context) − Executes prior everything.
  • after_feature(context, feature) − Executes post every feature.
  • after_scenario(context, scenario) − Executes post every scenario.
  • after_step(context, step) − Executes post every step.
  • after_tag(context, tag) − Executes post every tag.
  • after_all(context) − Executes post everything.

The project structure should be as follows −

Behave - Hooks

Feature File with hooks (Payment. feature)

The feature file with Behave hooks for the Payment. the feature is as follows −

Feature − Payment Process
Scenario − Verify transactions
         Given user makes a payment of 100 INR And user makes a payment of 10 Dollar

Feature File with hooks (Payment1.feature)

The setup functions include – browser open, database connection, configurations, and so on. Given below is the feature file with Behave hooks for Payment1.feature −

Feature − Administration Process
Scenario − Verify admin transactions
         Given user is on admin screen

Corresponding step Implementation File

The step implementation file is as follows −

from behave import *
from parse_type import TypeBuilder
parse_amt = TypeBuilder.make_choice(["100", "10"])
register_type(Amt=parse_amt)
parse_curr = TypeBuilder.make_choice(["INR", "Dollar"])
register_type(Curn=parse_curr)
@given("user makes a payment of {n:Amt} {t:Curn}")
def step_payment(context, n, t):
   pass
@given('user is on admin screen')
def step_admin(context):
   pass

Step 4 − Hooks in environment.py file

The hooks in the environment.py file are as follows:

# before all
def before_all(context):
   print('Before all executed')
# before every scenario
def before_scenario(scenario, context):
   print('Before scenario executed')
# after every feature
def after_feature(scenario, context):
   print('After feature executed')
# after all
def after_all(context):
   print('After all executed')

Output

The project structure should be as follows −
