Lightning Talks by Globant - Automation (This app runs by itself )
- 1. The power of automated testing GLOBANT We are
- 2. Is the process of operating a system or component to evaluate specific aspects under specific conditions, observing and registering the results. The process of executing a program with the intention of certifying its quality. TESTING PROCESS Testing is the art of destroying something constructively
- 3. Why is it necessary? Because errors exist...and humans **** up things. Testing helps us to: Ensures product fits customer's requirements Makes sure the code is reliable, helps improve developers knowledge/skills and overall product quality Reduce defects that can potentially reach Production environments Redefine the way things are done and how they work Set projects up to success As time passes, the cost of fixing a defect increases.
- 4. Approach Purpose Pros Cons Black Box Tests what the software should do Based on the module’s definitions and specifications Does not care about the program’s internals Functional test, produced by data, inputs and outputs Unbiased User based testing Requirement validation approach Testing each/every input is unrealistic. Insufficient time. Many paths go untested Hard to evaluate how much has been tested Suites grow fast. High maintenance of automated tests Test redundancy White Box Tests what the software does Test cases are designed considering the software’s internal structure Harder to validate requirements Development skills needed Cannot detect absence of functionality or misinterpretations Positive Verifies the ability of the system to implement a solution to the business needs under normal conditions Negative Verifies the ability of the system to detect, document and resolve user errors or any other condition not considered normal Testing approaches
- 5. Generally described within the functional requirements specification Refers mostly to “what the system does” These tests belong to the “Black Box” category Smoke testing: Refers to the first tests that are executed to provide quick feedback to determine if system under test is stable and won’t fail drastically Sanity testing: Refers to the suite of tests that is executed to verify the main functions of a system are working without errors to determine if it is reasonable to continue with further (more detailed) tests Regression testing: Consist in testing a system after a modification has taken place to verify that no new defects have been introduced or affected the previous correct functionality FUNCTIONAL TESTING TYPES
- 6. May include: Performance Stress Usability Disaster/Error Recovery Portability NON FUNCTIONAL TESTING TYPES
- 7. Automation Engineering aims to improve productivity and quality of repetitive tasks that are normally tackled by people. Increased throughput or productivity. Improved quality or increased predictability of quality. Improved robustness (consistency), of processes or product WHY DO WE AUTOMATE?
- 8. Faster time to market Reduced cost of failure Leverage Cumulative coverage BENEFITS
- 9. When is automating a good idea? Application stable Tests that use multiple data values for the same cases Tests that require detailed information about the internal state of the system (SQL, GUI, etc) Tests run in several environments)
- 10. When is automating not a good idea? Not final version of the app or systems in beta phase Tests that will be run only once Tests with little predictable results Unstable applications
- 11. MANUAL Manual testing vs Automated testing Success of the expertise of the performer Difficult to document Difficult to keep updated Automated The result does not depend on the performer Self-documented Auto-updatable if there are changes in the application
- 12. Record and playback Data driven Keyword driven BDD and Hybrid Selenium based frameworks. Do you want reinvent the wheel? Generations of test automation frameworks
- 13. Most popular Selenium IDE No code needed Hard to maintain Record and playback
- 14. Data Driven Testing Framework helps the user segregate the test script logic and the test data from each other External data from databases, csv, text files Data driven
- 15. Common functions to perform actions keywords are stored in a step-by-step fashion with an associated object. Object mapping More in-depth programming knowledge Keyword driven
- 16. Some of the top recognised automation QA engineers decided to crate frameworks “core” and share it with the rest of the world Much better to base your hybrid framework on them then reinventing the wheel. Barely support @Test public void userCanLoginByUsername() { open("/login"); $(By.name("user.name")).setValue("johny"); $("#submit").click(); $(".loading_progress").should(disappear); // Waits until element disappears $("#username").shouldHave(text("Hello, Johny!")); // Waits until element gets text } Selenium based frameworks
- 17. Behavior Driven Development frameworks allow automation of functional validations in easily readable and understandable format to Business Analysts, Developers, Testers, etc. Combination of one or more than one above mentioned. Users don’t necessarily need to be acquainted with programming. Adapted to get the best results Hybrid, the most popular approach nowadays BDD and Hybrids frameworks
- 19. Group of libraries that define coding standard , concepts, processes to support automated testing. So we can follow these guidelines while automating application to take advantages of various productive results. Reuse, coding faster... What is an Automation framework
- 20. How does an automation framework works?
- 21. Object mapping Steps Test cases Schedule How does an automation framework works?
- 23. The page object is a design pattern for enhancing test maintenance and reducing code duplication Page Object Model Clean separation between test code and page specific code such as locators and layout. Providing higher-level operations than the exposure of elements: for example, filling a form with a single method that contains default values for most of the inputs. It improves the readability and allows us to create interactive documentation POM creates our testing code maintainable, reusable.
- 24. The PageFactory Class in Selenium is an extension to the Page Object design pattern. It is used to initialize the elements of the Page Object or instantiate the Page Objects itself Page Factory we use annotations @FindBy to find WebElement. We use initElements method to initialize web elements
