Our Software Is Complex ….

We develop software in multiple locations─ Westminster, Colorado─ Alpharetta, Georgia─ Roseville, MN─ Bangalore, India

Using many development tools─ Java─ .Net─ GWT─ Standard HTML

New release contains 35 different applications and over 40,000 tests

5

Why Automate Our Tests?

Revenue: Faster time to adoption will speed license revenue recognition, market penetration

Cost: Reduced cost to execute tests Agility: Ability to run regression tests more

quickly to speed time to market of our products. Repeatability: Detect regression errors more

quickly without human errors or variability. Coverage: Increase platform coverage on each

release. Increased confidence in our application quality.

Status at the Start of the Project

2000 working automated tests using QTP These took 3 years to develop The team was using a keyword-driven

framework Tests were scripted using VB script (no record

and playback) Tests required a lot of maintenance and many

had to be abandoned There were many false failures

7

The Challenge!

5000 new working automated tests in one year─ Must be in production and executed successfully─ Broad product coverage

Be able to execute the tests in 3 days Tests must be re-usable over multiple releases

with a minimum of maintenance Automate first – SME Centric approach Use automated testing as part of agile

development process

Business Process Testing

HP’s Business Process Testing (BPT) product was selected for this project

The QTP framework had some problems we wanted to resolve:─ Tests still required a lot of maintenance─ Tests required automation engineers to write, and

they did not know the applications well enough to know what the tests should do

─ When tests failed the failures could not be resolved by the automation engineers (did not know enough about the app to know if it was a bug)

Advantages of BPT

Components are created by automation engineers who can create them without really knowing everything the application needs to do

Tests themselves are created by subject matter experts who know what the tests need to do and how best to prioritize them.

Test failures are analyzed by subject matter experts who know if it is a software defect or a problem with the automated script itself.

10

How to Select Good Candidates for Automated Tests

App must be in a technology that is automatable (no apps requiring reading of bitmaps).

Frequently run tests are automated first since they will give the greatest payback

This requires that a full risk-based analysis be performed on your regression suite to prioritize all regression tests

High-priority regression tests (wide and shallow) are the ones that should be automated for highest ROI.

11

Frequency of Automated Tests

Environmental Health Check – 1 hr. Can you log in to all apps? Executed on every build.

Smoke tests – 4 hrs. Can all main pages be accessed? Executed every two weeks.

Critical automated regression – 6 hrs. can all major transactions be performed? Executed at start of regression testing and also last thing before release.

High priority regression - executed several times on a release.

SME-centric Process Advantages

Responsibilities are clearly defined:─ Automation developers define architecture and create

components─ Subject matter experts create automated test cases

SME doesn’t need to know/use QTP. Uses very flexible Keyword/Data-Driven approach. Reduced learning curve due to same approach across

different applications/technologies Applicable to all areas of automated testing, like

regression, smoke, acceptance, etc. Designed for Maintainability

Automated Testing with Agile

Automation Engineers SME Testers

Shared between Agile teams Create BPT components

during each sprint Modify components as

needed

Embedded in Agile teams

Write automated tests using BPT components during each sprint

Execute automated tests at the end of each sprint

Use BPT tests as regression tests during later sprints

Benefits of New Approach

Leverage product knowledge of SMEs to write more meaningful and reliable tests

Increase test coverage -> fewer product escapes

Ability to keep up with increased product workload without increase in staff

Reduce time spent analyzing automation failures Faster execution of automated tests

The Results

The team created 5500 new, working BPT tests in one year using this approach.

With the same budget, the team increased the number of automated tests created by 5 times using this approach.

Automated tests now comprise 25% - 40% of the tests executed depending on the size of the release.

These tests are being maintained and executed consistently.

The team is now working on maintenance, speed of execution, unattended execution, and new projects.

CREATING REUSABLE BPT COMPONENTS

Step 2

26

Business Components

A component is a reusable module to perform tasks on logically independent application parts (Page or Window).

Components use Input/Output parameters for data input/verification and navigation within Page or Window.

Input/Output parameters also are used to pass data between components.

Components can use iterations.

Login Component Steps(Example for Web Application)

Component initialization─ Load environment variables like URL, login

credentials, DB connection strings, etc. Close all browsers except QC Invoke an application Login Verification that login is successful

Functional Component Steps (Example for Web Application)

Component initialization – ComponentInit() function─ Load environment variables like URL, login

credentials, DB connection strings from Environment.xls file using QC OTA

Verify that Expected page is displayed Side or Top menu navigation Web Page internal flow

Data

Parameter Naming Conventions

Prefix Object Example

lst List lst_User

txt Edit txt_User

chk Checkbox chk_User

rad Radiobutton/RadioGroup rad_User

tab Tab tab_User

tbl Table tbl_User

cell Cell in Table cell_User

file WebFile file_User

ele WebElement ele_User

cmb Combobox cmb_User

st Static Text (Read Only) st_User

.Apply Method

Object.Apply Parameter(“Parameter_Name”).WebEdit(“Name”).Apply Parameter(“txt_Name”)

Apply method functionality:─ Performs data substitution─ Verifies if object exists and visible─ Makes decision what to do with “Name” edit object

based on Parameter data

Input Constraints for Edit (Text Box) Object

Value Action Example

No action

<CLEAR> Clear edit field <CLEAR>

text Enter text Hello

[text] Verify text [Hello]

[<ENABLED>], [<DISABLED>] Verify if object is Enabled/Disabled

[<EXIST>],[<NOEXIST>] Verify if object exist/no-exist

[<REGEX>Pattern] Verify that Pattern matches text

[<REGEX>TestCase.*]

Working with Objects in Grids

row=WebTable().GetRowIndex(Parameter(“search_”),clmn)WebTable().CellApply row, clmn, objType,

Parameter(“cell_”)iRow = WebTable().GetRowIndex(Parameter(“search_Name”),2)WebTable().CellApply iRow,3,“WebElement”,”Parameter(cell_Age”)

Parameter prefixed with the word “search_” indicates which row to work with.

─ Row can be selected by using row number: #n ─ the text contained in the specified Column─ Pattern

Parameters for objects in table cells are prefixed by “cell_”

Example: Working with Grids

Data Substitution

Special tags for Dates, Times, SSNs, Unique values, DB Queries, Random, etc.<SSN> - get substituted with unique SSN<TODAY> - get substituted with today date (03/19/10)<RNDDIG 3> get substituted with 3 random digits<DateTime YYYYMMDDHHmmss><DB DBEnvironment::SQLStr>

Tags can be combined[<REGEX><TODAY> at .* AM]

Summary

This method provides a way for test automation engineers to create re-usable components without having to know all the ways the application will be used.

Subject matter experts can use the components to easily create tests that can do anything that the application can do without having to be software engineers.

This method allowed us to create a great number of working automated tests in a relatively short time.

The project has been a major success and has helped us achieve greater confidence in our release quality.
