MOBILE
PHONES ARE
PART OF OUR
LIFE
And application that written for smartphones are critical
important to be stable and work well

5. UkrainQA #7
Except of comprehensive automation planning
process, maintenance of your test-cases, manual
testing with all possible design technics, there are
three parts of go
Write
good
code
Collaborate
with your
team
Make a robust
scalable
infrastructure
5
THREE PARTS
OF SUCCESSFUL
AUTOMATION

6. KISS your code
6

7. UkrainQA #7
Code is compiled,
tested and works
as expected
Code is
commented and
documented
Code is readable
understandable,
for other team
members
Code is scalable,
reusable

WHAT IS
GOOD AUTOTEST?

8. KEEP IT SIMPLE
8
and stupid

9. UkrainQA #7
It’s not silver bullet, but could help in
particular situations
Don’t reinvent the wheel.
Reuse already written code if it is from
reliable sources
Patterns External Libraries New language features
9
HOW TO DO IT?
Don’t forget to learn new

10. UkrainQA #7 10
PATTERNS:
BUILDER
Could be used for building complex object in
an efficient and convenient way

11. UkrainQA #7 11
PATTERNS:
VALUE
OBJECT
It’s easier to operate with complex objects
instead of simple ones

12. UkrainQA #7 12
PATTERNS:
CHAINING
Sequential methods calling could be readable
for some cases, and it simulates user steps

13. UkrainQA #7 13
PATTERNS:
DATA
PROVIDER
Thanks to data provider, the Data Driven
approach could be used for tests

14. UkrainQA #7 14
PATTERNS:
OBJECT
POOL
Borrow unique objects without explicit
initializing

15. UkrainQA #7 15
PATTERNS:
STRATEGY
Implement different strategies for some
action to boost your tests

17. UkrainQA #7 17
EXTERNAL
LIBRARIES
A library is a collection of class definitions and its implementations.
The main benefits of creating library is simply code reuse.

18. UkrainQA #7 18
My personal choice
AssertJ
Fluent assertions for java
Selenide
Allows you to simplify your tests
Allure
An open-source framework designed to create test execution reports that are clear to everyone in the team
Slf4j
Simple Logging Facade for Java
REST-Assured
REST Assured is a Java library that provides a domain-specific language (DSL) for writing powerful, maintainable tests for RESTful APIs
LOMBOK, OKHTTP/RETFROFIT, GSON, APACHE COMMONS POOL, GOOGLE AUTOVALUE, ETC.
There are a lot of other cool libraries...

19. UkrainQA #7 19
LIBRARIES:
AssertJ
Flexible approach for assertions

20. UkrainQA #7 20
LIBRARIES:
Selenide
Selenide is not only for web tests

21. UkrainQA #7 21
LIBRARIES:
Selenide
It’s also applicable for mobile testing

22. UkrainQA #7 22
LIBRARIES:
Allure
Just really nice reports :)

25. A FEW MORE
THINGS

26. UkrainQA #7
I
26
DON’T
FORGET
ABOUT
LOGGING

27. UkrainQA #7 27
TIPS:
LOGGING
Logging helps you to figure out what is going
on in your tests

28. UkrainQA #7 28
NEW LANGUAGE
FEATURES
Stay tuned with new java features

29. UkrainQA #7 29
JAVA 11:
Local
Variable Type
Inference
Java 10 has introduced a new language
keyword var which optionally replaces the
type information when declaring local
variables (local means variable declarations
inside method bodies)

30. UkrainQA #7 30
JAVA 11:
HTTP Client
Java 9 introduced a new incubating HttpClient
API for dealing with HTTP requests. As of Java
11 this API is now final and available in the
standard libraries package java.net.

31. UkrainQA #7 31
JAVA 11:
Collections
Collections such as List, Set and Map have
been extended with new methods.

32. UkrainQA #7 32
JAVA 11:
New features
in streams
The methods dropWhile and takeWhile both
accept a predicate to determine which
elements to abandon from the stream

33. UkrainQA #7 33
JAVA 11:
New features
in Strings
One of the most basic classes String gets a
few helper methods for trimming or checking
whitespace and for streaming the lines of a
string

34. INFRASTRUCTURE

35. UkrainQA #7
To keep a finger on the pulse of our quality:
● We’ve got the testing results after each build
● We’ve got the results of regression testing
every night
● Data generation is automated as well

APPIUM
vs
Espresso &
XCUITest
What’s to choose?

37. UkrainQA #7
Repository
We use Bitbucket as a
main repository
Unit &
Integration
Espresso and JUnit, classic
:)
UI tests
Appium + TestNG +
STF + Allure
37
OUR TOOLS
CI
We use Jenkins as our
Continuous integration
tool with multi branch
approach

38. UkrainQA #7 38
INFRA:
Jenkins
Blue Ocean
One of the most basic classes String gets a
few helper methods for trimming or checking
whitespace and for streaming the lines of a
string

39. UkrainQA #7 39
INFRA:
A branch for
an each issue
you work on
Then do all the implementation and testing
work on that branch. When that's complete,
submit a pull request, merge up, and release
whenever you're ready.

HOW TO INSTALL
OPEN STF
Requirements:
Node.js >= 6.9 (latest stable version I found node@8)
ADB properly set up ($ANDROID_HOME is set for your system)
RethinkDB >= 2.2
GraphicsMagick (for resizing screenshots)
ZeroMQ libraries installed
Protocol Buffers libraries installed
yasm installed (for compiling embedded libjpeg-turbo)
pkg-config so that Node.js can find the libraries
Note that you need these dependencies even if you've installed STF
directly from NPM, because they can't be included in the package.
On Mac OS, you can use homebrew to install most of the
dependencies:
brew install rethinkdb graphicsmagick zeromq protobuf yasm
pkg-config
As mentioned earlier, you must have all of the requirements installed
first. Then you can simply install via NPM:
npm install -g stf

46. UkrainQA #7 46
HOW TO RUN
OPENSTF
Launch database:
rethinkdb --http-port=8081
Launch stf:
stf local

47. WHAT ABOUT DOCKER?
47

48. UkrainQA #7 48
INSTALL JENKINS
Install docker, and then run command:
docker run
--rm
-u root
-p 8080:8080
-v jenkins-data:/var/jenkins_home
-v /var/run/docker.sock:/var/run/docker.sock
-v "$HOME":/home
jenkinsci/blueocean
After that, proceed with wizard to complete installation
process

49. UkrainQA #7 49
HOW TO INSTALL
OPEN STF
clone https://github.com/nikosch86/stf-poc
Then change public ip in .env file
And run command:
docker-compose up -d —build
