Quality Assurance Guidelines for Mobile App Development

Moqod quality assurance
guidelines

02
Vision:
At Moqod it’s our main goal to deliver high-quality software. Ideal world software
quality standard is completely bug-free software. We strive to deliver bug-free
software.
Deﬁnition of a bug:
Bug is an error, flaw, failure, or fault in a computer program or system that causes
it to produce an incorrect or unexpected result, or to behave in unintended ways.
(Wikipedia).
key points

03
Quality standards:
Therefore software quality standard at Moqod is simple and straight forward -
“Software functions as expected”. As expected means as speciﬁed and described
in the project functional documents and artefacts.
But this doesn't mean blindly following the docs. Because of continuous
communication with the customer, “software functions as expected” also means -
as expected by the customer and the end-user.
key points

04
The following points apply to all projects to ensure highest possible quality of the
software products:
● Moqod employs a dedicated full-time QA engineer.
● QA engineer must be introduced to the project at the earliest stage possible.
● All issues must be reported and document to a tracking system! Otherwise
the issues can be disregarded. This concerns all project stakeholders (dev
team, QA engineers, PMs, Customers etc).
general rules

05
● QA engineer at Moqod is the main quality gate.
● We praise proactive approach in solving problems. This includes: fast
reaction on reported issues, self-driven problem solving, looking at all
possible sources to quickly localize and solve a problem.
● We praise transparency through our whole workflow. The customer is in
direct contact with the team and is encouraged to ask/answer questions
from the team.
● Device, browser and OS compatibility will be stated in the project
speciﬁcation. The product will be tested in these environments.

Code review is the ﬁrst step in delivering quality software. It helps to identify
potential errors at early stages. Currently at Moqod P2P code review is in place.
Code review is done in the following way:
1. All developers pair up.
2. Every day every developer spends up to one hour to review the code of his
partner. One developer shows pull of changes during the last 24 hours and
describes the tasks he had to resolve. His partner evaluates the solution and
adds his comments or suggestions. Once the review is done, developers
switch roles.
3. Every month tech lead reviews and when needed changes the pairs.
code review process
The main advantage of this approach is that the reviewer understands
the context and all details of the solution from his partner.

Automated test scripts
AWS Device Farm

10
For the maximum coverage of test devices Moqod offers automated testing using Amazon Device
Farm and automated test scripts. This is an optional item that can be added to a project quote.
How this works:
1. Create a list of test cases for the app. Coverage to be discussed.
2. For iOS Apple UI automation is used as an instrument. For Android Robotium Framework.
3. These scripts will be run on AWS Device Farm to perform the test cases on the target
devices.
4. Afterwards the test scenarios can be run at any time with a mouse click, automating
regression tests.
Important:
AWS Device Farm uses real devices, so we get a coverage and environment close to real life.

12
It is highly recommended to cover backend (web API calls, database calls,
front end and admin section) with unit tests and run these automatically on
staging environment with every deploy.
This ensures all APIs and so clients (mobile, front-end etc) will remain
intact and will funcion properly. Otherwise, the problem can be identiﬁed at
the moment changes are deployed to staging.
API Unit tests

13
Due to the speciﬁc nature of mobile development (data access, device
location, different hardware and software environments etc) manual testing
is the key component in QA process. During the manual testing we use
various monkey scripts and monitoring tools for all mobile platforms.
Manual testing process

rules and guidelines for
manual testing process

15
1. QA engineer reviews project documentation. 
a. Documentation is sufﬁcient – go to step 2.
b. Otherwise, the documentation is to be revised by the Customer and PM.
2. QA engineer estimates the amount of work needed for testing.
3. The team plans iterations and release dates for interim milestones and
ﬁnal release.
Stage 1.
QA Planning

16
1. At the end of every iteration upon delivery of an interim milestone a testing
round is held.
a. Functional tests are executed on newly delivered features.
b. Regression tests are executed on previously delivered features.
Stage 2.
Interim release testing

17
2. The results of interim release test are:
a. Delivery successful. QA engineer approves the release. The build is sent to
customer together with a short report containing release notes. Go to step 3.
b. Delivery failed. QA engineer rejects the release. The build is not sent to
customer. A report with action plan is provided to customer. The release is sent
back to dev team for the needed ﬁxes. However, a PM can still provide the build
to Customer to showcase the progress.
Stage 2.

18
3. Customer receives the build. Possible actions:
a. Customer accepts the build and signs off the milestone as is.
b. Customer rejects the delivery and the release is sent back to dev team for the
needed ﬁxes.
c. Customer accepts the build and signs off the milestone, but with minor
feedback and comments. This feedback is added to backlog for future
releases.
Stage 2.

19
1. Upon reaching ﬁnal milestone a complete acceptance test is executed on the
product. QA engineer reviews all use cases to check against the actual functionality
of the product.
2. GUI testing is held on the ﬁnal delivery. All screen dimensions, fonts and colors
need to be checked.
Stage 3. Final release.
Acceptance testing.

20
3. The results of Acceptance testing can be:
a. Release accepted by QA engineer. The build is sent to customer
accompanying acceptance report. The report contains a list of all use cases
and test results against the use cases (success/failed). The product is
provided to customer for sign off.
b. Release is rejected by QA engineer. The product is not provided to customer
for acceptance. A report with further action plan is sent.
Acceptance testing.

21
4. Customer reviews the ﬁnal product delivery:
a. Customer accepts the delivery and signs off the project. The product is
processed to Store upload or live environment.
b. Customer accepts the delivery and signs off the project, but with some
comment or improvements. The product will still be sent to store or live
environment. The feedback will be taken into new version of the product as a
separate statement of work
c. Customer rejects the delivery and the release is sent back to dev team for the
needed ﬁxes.
Acceptance testing.

QA Engineer responsibilities
and authorities

23
At Moqod a QA engineer is the main jury who is in charge to accept or reject the
work. The list of responsibilities of a QA engineer is the following:
● Accept/reject deliveries.
● Help ﬁnd the root cause of a problem.
● Review and accept/reject project documentation.
● Report to PM and dev team upon results of testing.
● Set speciﬁc rules for QA process on projects.
● Ensure all project stakeholders follow the rules and process.
