Today’s Testing Challenges

• Need to test as early in the cycle as possible

• Execution time is critical: tests must run as part of the CI/CD

• Multiple platforms, devices, languages, etc.

• Shorter than ever stabilization time (if any at all)

• Applications are becoming more complex and fragmented than ever

• User Experience (UX) expectations have raised – users expect nothing less than perfection

• Increased usage of 3rd party integrations (Twitter, Facebook, PayPal, AWS, etc.)

UI Testing

Pros

• Tests the actual interface as the real user

• Covers Business Flows

• Can be easily covered in manual testing

• Automate once, run all the time

• Covers application areas that don’t have unit tests

• Detects differences in behavior between platforms

Cons

• UI Stability: usually stabilized late in the cycle

• Maintaining UI objects in case of change

• Increased support matrix

• OSs, browsers

• Mobile: devices, platforms

• Execution time longer compared to API testing

Protocol Usage by APIs

APIs, Micro-Services, IoT, Sensors, Beacons, etc.

UI-less Testing is on the Rise

• Teams are required to test early in the cycle, when the UI is not ready

• 20% want to involve testers earlier

• Public APIs (and the API business model) are being exposed as part of the product offering

• Raise of 53% in Public APIs available since 2013 (programmableweb.com)

• Your front-end may be a device with no monitor

• Single-page apps

• APIs will become the actual product

• IoT, computing everywhere

Today

Tomorrow

API Testing

• Can be done earlier in the cycle

• Early feedback for the core business logic

• More stable than the UI

• Same services can be used across all devices and platforms. Device specific tests can be completed later.

• Runs faster than UI tests

• Can be used for quick data population

• Tests & validates functionality that might not be exposed in the UI

Cons

• Requires a more technical skill set

• Harder to build the business flow

• Still need to test the UI

• Testing without a business context

Pros Cons

Database Engine Ranking

Database Testing

• Data is an important asset in the system

• Some code (functions, procedures) is stored and run in the database itself

• Populate your databases as part of your tests

• Easily extract tokens and information to be used in UI testing

• Scripting, query, and DB specific skills are needed

• Testing without a business context

• Harder to build the business flow

• Databases are not always accessible

• NoSQL databases are more complicated to access

The Forrester Wave™: Modern Application Functional Test Automation Tools, Q2 2015

by Diego Lo Giudice, April 17, 2015

“Target 80% Functional Test Automation and 20% manual testing.

To reach around 80% of FTA, Agile teams test at the API level. ……Ratchet down UI test automation in favor of API test automation. Modern applications Modern applications require a shift of the current 80% UI automation down to 5% to 10% approximately, shifting about 80% of that test automation to be replaced by API test automation. “

Our Own Best Practices

• Focus on API testing early in the cycle. Complete the UI coverage only when it is stabilized.

• Don’t work on an “empty” system. Populate it using your DB and APIs.

• Each test should be independent of other tests (for parallelism, easier investigation, etc.).

• Use the APIs as the test setup and continue with the UI for the core functionality test only.

• Run your tests as part of your CI/CD process: the entire suite should run for no more than a couple of minutes, preferably API testing only, and provide core functionally feedback.

• Run your complete suits as part of the nightly build.
