Using SOQL with APEX

Where can we do this?

Most important thing we learn!

95% of triggers

Beyond workflow – Cross multiple objects

Which of these movies is overrated?

#forcewebinar

Deduping Trigger

1. Lead is created or updated

2. Lead has an email address

3. Try to find matching contact based on email address

4. If match is found, populate a Dupe_Contact__c lookup field

5. If match is not found, clear the value of Dupe_Contact__c lookup field.

#forcewebinar

Exercise

Let’s write a Deduping Trigger!

#forcewebinar

POP QUIZ!

Without SOQL, what fields are available for each record entering a Trigger?

What character must be placed before every Apex variable used in a SOQL query.

What are the three uses of Dot Notation?

A colon! (:)

Only fields directly on the record are available – related fields are not!

- Access fields- Traverse relationships- Use methods

4 Principles of a Good Test Class

1. Create Records From Scratch

2. Be “Assert”-ive

3. Break Things!

4. Be “Bulky”

#forcewebinar

Principle 1: Create Records From Scratch

#forcewebinar

Principle 2: Be “Assert-ive”

#forcewebinar

Principle 3: Test Things That Should Not Work

#forcewebinar

Principle 4: Be “Bulky”

#forcewebinar

SOQL APEX Challenge!

Other than testing in bulk, which testing principle is this class missing?

First listener to guess via CHAT wins a Developer Prize Package!

#forcewebinar

Other than testing in bulk, which testing principle is this class missing?

Test things That Should Not Work – Negative Testing

#forcewebinar

Exercise!

Let’s write a Test Class for our Deduping Trigger!

#forcewebinar

POP QUIZ!

Why shouldn’t a developer query for production records in a Test Class?

Why should every test class use System.assertEquals() even if your code works 100% of the time?Your code may break in the future as your org changes over time. For example, a new validation rule could prevent one of your triggers from updating certain records. System.assertEquals() will alert you of these scenarios before you find out the hard way.

Test code runs without any existing data from both your sandbox and production database! You should always create records from scratch, otherwise you risk test failures down the line.
