About Tusha

Tusha leads the QA department at HelloSign.com, one of the major key players in the field of electronic

• signatures. Along with a Masters in Computer Science, I have several (12+) years of software industry

experience in the areas of both quality assurance and development. My career spans from being a Java developer to a Management professional, during which I have been passionate about not only coding in Java and C#, but also the many facets of quality assurance like UI/API/Automation. I also have been playing a key role in advocating the importance of various Agile techniques in determining the ultimate quality of the software product, thereby strengthening the Product/Development/QA teams!

Objectives

• The main purpose of this presentation is to focus on the end to end practical

knowledge of SQA - it’s role, deliverables and the processes involved in SDLC (Software Development Life Cycle)

• Key takeaways include:
• Understanding how SDLC works in different methodologies.
• Fundamental knowledge of Different roles of QA in a product life cycle.
• Team collaboration between Dev/Product/QA.
• Software QA deliverables.
• Practical approach to deliver a high-quality product on time.

Software Development Life Cycle (SDLC)

• What is SDLC?
• Phases of SDLC
• Models of SDLC
• Waterfall
• Spiral
• V&V
• Iterative
• Big Bang
• Agile

Agile - Process

Important Keywords and Concepts:

• User stories
• Scrum Boards
• Sprint Backlogs
• Burn down charts (and other charts)

Standard Sprint workflow: User Stories -> Implementation/Functional Testing (QA env) -> Deployment to Staging/Preprod -> Regression tests (manual/automated) on Staging -> Release to Prod -> Sanity tests (manual/automated) on Prod.

User Stories

• What is a user story?
• How is an user story useful in an Agile?
• Why is the user story the most “crucial” component for

testing? ○ Acceptance Criteria

Acceptance Criteria - Deep Dive

Example user story: As an existing user of HelloSign, I want to be able to see the signed signature requests from signers, so that I know that my signature requests have been signed. Example acceptance criteria:

• The Documents page is displayed.
• The Documents page should have sections that indicate different statuses'.
• The Documents page should display a section with with Completed signature requests.
• The Completed signature request should have options to Preview/Download the signature request.

Agile Management Tools

Some of the common Agile Management tools:

• JIRA
• Rally
• Version One
• Pivotal Tracker

JIRA:

• Workflow Stages

JIRA - Workflows/User Story

Collaboration

• Role of QA in a software project.

○ Importance of QA/Test team.

• Collaboration with Dev team.ç
• Association between QA and Product teams

Automation

Selenium - Introduction & Basics

➢ Open source ○ Originally developed at ThoughtWorks. ○ Free. ○ Download and install. ➢ Multiple language support ○ Java, Php, Ruby, C#, Python etc. ➢ Selenium IDE ○ UI Based tool. FireFox add-on. Record & Play. Generates code/script which can be modified. ➢ Selenium RC ○ Server written in Java. ○ Client drivers in different languages. ○ Deprecated now. ➢ Selenium WebDriver ○ Uses a Client API to send commands to browser via drivers (Firefox, Chrome, Edge, IE etc.,) ○ HtmlUnit browser or Headless browser. ➢ Selenium Grid ○ Server that enables web browser instances to run on remote machines. ○ Hub -> Servers -> WebDriver nodes (browser instances)

WebDriver - Basics

An web element (UI element) can be located using:

• 1. By ID
• 2. By CSS
• 3. By xPath
• 4. By Tag Name
• 5. By Class Name
• 6. By Name
• 7. By Link Text

Selenium - Maven Dependency

WebDriver - Page Object Model

Example - Folder Structure ➢Maven project (Java)

○ Main/Java ■ Core ■ Utilities ■ Locators ■ Implementation ■ Page Objects ■ Test Data ○ JUnit/TestNG ■ Test classes

JUnit/TestNG Test Classes Example - GoogleSearchTest.java This will the test implementations of the page object methods. In this example, the methods - searchForHelloSign() and selectHelloSign() will be run as tests. A single test case can be created individually or test suite can be created.

Reports in Automation

While there are a few plugins available to report inbuilt reports in automation, below is one of the most common plugin - SureFire, where the test results can be generated in HTML format. Maven Surefire plugin and below is the screenshot as to how to integrate it as a dependency within the Maven configuration (pom.xml).
