Have questions?

§  We have an expert support team at the ready to answer your questions during the webinar.

§  Ask your questions via the GoToWebinar Questions Pane.

§  The speaker(s) will choose top questions to answer live at the end of the webinar.

§  Please post your questions as we go along!

§  Only post your question once; we’ll get to it as we go down the list.


Agenda

§  Testing Apex •  Why test?

•  When test?

•  How test?

§  Code Coverage

§  Advanced Debugging •  Log Inspector

•  Checkpoints

–  Set checkpoints

–  View memory contents

–  Inject logic


Assumptions

This webinar assumes the following: §  You know…

•  …what Apex code is

•  …how to launch the Developer Console

§  You have… •  …used the Developer Console before

•  …done debugging before

But don’t worry, you can catch up via these resources: http://wiki.developerforce.com/page/Webinar:_Intro_to_Apex_Code_(2012-July)


Why test?


Testing Protects You From Others


Testing Protects You From Us


When should I test?

Write tests throughout development §  Before development

§  After development

§  In their own @isTest classes

You should test frequently! §  During development §  Before deployment

§  During deployment

§  During release preview window


How can I run tests on my code?

Salesforce provides several avenues for test execution §  Developer Console

§  “Setup” User Interface

§  Automatically during deployment

§  Through the Tooling API *COMING SOON!*


Developer Console


Testing in “Setup” User Interface


Asynchronous Test Execution

Salesforce runs your tests in the background so they can be processed as resources allow.

§  Asyncronous testing runs tests in no particular order

§  It allows you to see status of tests as they complete

§  The process is integrated into developer console


Code Coverage

We store the results of your testing to calculate code coverage, and show you these stored results in the developer console.

§  Aggregate coverage for each class and trigger

§  Coverage by each test method on each class and trigger

§  CAUTION! These results are stale as soon as you change the test or the class


Let’s See The Demo Already!


Use Case: UberJet


Debugging Code


Debugging with the Log Inspector

§  Execution Log •  The entire transaction, line by line and more

§  Source / Variables •  Current code location and variable values

§  Stack •  How you got where you are

•  How long each step took

§  Execution Overview •  Limits

•  Performance per action, per method


When the log is not enough…checkpoints!

A checkpoint is like a breakpoint, but cloud-approved §  Heap

•  Provide a view into the memory at the checkpoint

§  SOQL query •  Run a SOQL query at the checkpoint

§  Apex Code •  Inject a miniature apex snippet at the checkpoint


Recap

§  Testing Is Important, Testing Is Easy •  Test always

•  Use the Developer Console to see results and code coverage statistics

§  Debugging Is Hard, Debugging Can Be Easier •  The Log Inspector provides many views into the haystack

•  Use Checkpoints to see the state of the world at a critical point
