Seminar on software

Your virtual training gave me the intuitiveness and confidence to think outside the box and apply something new, and it worked! Heather J. Mowry, MPA.

Easily schedule new seminars Seminar templates and presets automatically pre-populate information making scheduling seminars that re-run on multiple dates and locations easy.

Different types of seminars Manage seminars run at a physical venue , live online webinar style , or offer the option to complete the activity self-paced online. Automated communication Arlo manages all seminar communication for you.

Other features in Arlo Seminar Management System Sessions Include a choice of sessions as part of the main seminar and allow registrants to select the ones they would like to attend. Options and tickets Include additional seminar options such as tickets, dinner, and accommodation. Tasks Manage tasks associated with a seminar such as booking a venue and confirming attendee numbers before the start. Scheduled reports Schedule reports such as seminar attendee reports to be automatically sent to presenters before the seminar starts.

Printable certificates Create and send printable certificates for seminar attendance and completion. Statement coverage All statements in a method have been executed at least once Why is statement coverage is not enough Statement coverage can be achieved without exercising all branches Single loop iteration can cover all statements but may not reveal loop control bugs Statement coverage can be achieved without exercising all true-false combinations of conditions Dr.

Who does the coverage calculation? Yes, you can! Use Cobertura integrates nicely into Maven and Hudson Dr. What about Testing in Isolation? Always possible; but dependencies must be simulated Stubs or mocks Stubs Provide answers to calls made during tests. Demo Unit Testing in uDoo Integration Testing Integration Testing Integration testing is a search for components faults that cause intercomponent failures Breaking up component isolation step-by-step Integration strategy Which components are the focus of the integration test?

In what sequence should component interfaces be exercised? Integration testing in object-oriented development begins early Within a class integrating methods Within a class hierarchy integrating superclasses Between a client and its server Within a package integrating classes Bottom-up Integration Demonstrate stability by adding components to the system under test in uses-dependency order, beginning with components having the fewest dependencies Approach Test leaf components in dependency graph with drivers for each leaf.

Use doubles when necessary Repeat: test components on the next level; until the entire system is tested Dr. Bottom-up Integration Advantages Early integration of leaf components Parallel development on components in subtrees of dependency graph Reduces the number of doubles only for cycles Disadvantages Many drivers have to be developed Interaction testing is limited to collaborations implemented in the component root of subtree Postpones checking critical control interfaces and collaborations until the end root of dependency graph Dr.

Collaboration Integration Demonstrate stability by adding sets of components to the system under test that are required to support a particular collaboration Approach Map collaborations onto the dependency graph Choose a sequence in which to apply testing on collaborations Test collaboration in the chosen sequence Dr. Collaboration Integration Advantages Few drivers and doubles necessary Focus on end-to-end functionality; useful for system scope testing Reuse of collaboration integration test suite for system test Disadvantages Inter-collaboration may not be tested thoroughly Participants in a collaboration are not exercised separately big bang Probably many doubles for testing initial collaborations Dr.

Backbone Integration Combination of top-down integration, bottom-up integration, and big bang integration to verify interoperability among tightly coupled subsystems Used, for instance, for embedded system applications Backbone provides services that are essential for running tests and the application Creating doubles for the entire backbone would be impractical Approach Test each component in backbone in isolation and do a bottom-up integration or big bang integration of the backbone Do a top-down integration on the application control components Dr.

Backbone Integration Advantages Mitigates the disadvantages of top-down and bottom-up integration Disadvantages Doubles and drivers are necessary Dr. Integration Testing and Continuous Integration Demo Integration Testing for uDoo GUI and System Testing Demonstrate that the system implements all required capabilities.

Two-step approach UI Integration test Verify if UI interaction works as intended with the subsystem User story or use case testing with UI Validate if system works as intended when simulating user stories or use cases with UI interaction Dr. User Story Testing Develop a system test suite by simulating a user story Difference to integration testing User stories cover a chain of actions Integration testing starts over for each test case Approach Write down a story that covers all features of the application Specify a test case that runs the story as a system test including UI interaction Verify consistency after each feature invocation Use coverage tool to verify that each method was called at least once Dr.

Regression Testing Regression Testing Regression test suite is a set of existing test cases Does not contain tests for new or changed functionality Plays an important role in revealing bugs The software failure in the Ariane 5 rocket controller was in large part due to an assumption that previously tested code would work when it was reused, obviating the need for regression testing.

Regression Testing - When and How When a new subclass has been developed Rerun the superclass test cases on the subclass, beside new test cases for the new subclass When a superclass is changed Rerun the superclass test cases on the superclass and on its subclasses. The return value may cause a failure of B Dr.

The requirements the algorithm , and the code did not change An undesirable feature interaction occurs between B and D Dr. Highest run cost Generality: Can always be applied. Easy to set up, no analysis or special development is necessary Dr. Retest Risky Use Cases Use risk-based heuristics to select a partial regression test suite. Run this subset on a delta version Suspicious use cases: Select use cases that depend on components that are individually unstable or unproven have not been shown to work together before implement complex business rules have a complex implementation were subject to high churn during development many changes spread all over the system Dr.

Retest Changed Code Use code change analysis to select a partial regression test suite. Run this subset on a delta version Procedure 1. Use Cobertura to check which test case cover which source code parts 2.
