WHAT IS TEST DATA? WHY IS IT IMPORTANT?
1. A single Selenium test should test one and only thing. A bug in another part of the application
that is not exactly related to the test should not cause the test to fail.
2. Every test should be independent. The test outcome should not affected by another test in the
suite.
3. Make a faster tests. As quicker test suite as much useful it is.
4. Every test should create and clean the data before and the after the test run.
When we are talking about best practice in Selenium test,
some of things often come up are:

The reason for this is that
Selenium tests often involve
setups that may include
Only after doing those things
you are ready to assert
on some aspect of the website
 Actions
Sign up   Interactions

7. Test Data Preparation via HTTP requests

BASIC IDEA BEHIND COMBINING THESE TOOLS
These are the steps how to get started with OKHttp and Test Data Preparation
FIRST STEP
We will be creating
instances of HTTP
for various methods
like GET,PUT,POST
etc. by mentioning
the request URL
SECOND STEP
We will be
composing the
request body as
JSON
THIRD STEP
Execute the desired
HTTP method when
headers etc are all
set
FOURTH STEP
Capture the
response and
convert it to a JSON
object.
FIFTH STEP
Desterialize JSON to
any Java Object

25. Best Practice vs. Bad Practice

26. SQA Days 2017

BEST PRACTICE VS. BAD PRACTICE
Use PageObjects
pattern

27. SQA Days 2017
27
BEST PRACTICE VS. BAD PRACTICE
XPATH is the best
selector to use
#
Preferred selector order : id > name > css > xpath

BEST PRACTICE VS. BAD PRACTICE
Automate
CAPTCHAS
#
CAPTCHAs can be bypassed using two strategies:
• The first idea is to disable CAPTCHAs in your test environment.
• The second idea is to add a hook to allow tests to bypass the CAPTCHA.

BEST PRACTICE VS. BAD PRACTICE
Gmail and Facbook
Logins
#
WebDriver is not the ideal choice to automate login into websites like Gmail and Facebook,
firstly because it is against their policy and secondly because it is slow and unreliable.
The most appropriate choice would be to use the API that these websites provide.

BEST PRACTICE VS. BAD PRACTICE
Performance Testing
Using WebDriver
#
Using selenium WebDriver is not an ideal choice for performance testing, not
because it can’t do it but because it is not meant for this job ultimately tester might
not get good results.
