    Write focused test classes that cover all trigger paths.

    Problem Explanation

    Salesforce requires 75% overall coverage and trigger execution during deployment.

    Root Cause(s)

    1. Missing test data
    2. Trigger logic depends on existing records
    3. Unhandled branches

    Step-by-Step Solution

    1. Create test data inside @testSetup
    2. Cover insert, update, delete scenarios
    3. Assert outcomes

    Edge Cases & Variations

    1. Flow-triggered logic also needs coverage
    2. SeeAllData=false may hide dependencies

    Common Mistakes to Avoid

    1. Relying on org data
    2. Ignoring negative test cases

    Problem Explanation

    CI environments expose hidden dependencies and stricter validations.

    Root Cause(s)

    1. Hardcoded IDs
    2. Missing test data
    3. Environment-specific automation

    Step-by-Step Solution

    1. Remove hardcoded references
    2. Create complete test data
    3. Disable conflicting automation if needed

    Edge Cases & Variations

    1. Sandboxes differ from production
    2. Feature flags affect behavior

    Common Mistakes to Avoid

    1. Relying on org configuration
    2. Ignoring CI logs

    The connected app or user lacks required permissions.

    Problem Explanation

    Salesforce enforces OAuth scopes, object access, and IP restrictions on API calls.

    Root Cause(s)

    1. Missing API Enabled permission
    2. Insufficient OAuth scopes
    3. IP relaxation not configured

    Step-by-Step Solution

    1. Verify user profile permissions
    2. Check Connected App OAuth scopes
    3. Review IP relaxation settings

    Edge Cases & Variations

    1. Community users have limited API access
    2. Named Credentials simplify auth issues

    Common Mistakes to Avoid

    1. Using wrong user for integration
    2. Ignoring permission sets

    Why does my validation rule fail during data migration?

    Ken Adams Begginer

    Validation rules apply during imports unless bypassed. Problem Explanation Data Loader, APIs, and integrations enforce validation rules just like UI operations. Root Cause(s) 1.

    Validation rules apply during imports unless bypassed.

    Problem Explanation

    Data Loader, APIs, and integrations enforce validation rules just like UI operations.

    Root Cause(s)

    1. No bypass condition
    2. Required fields missing in import
    3. Incorrect formula logic

    Step-by-Step Solution

    1. Add custom permission bypass
    2. Assign permission to integration user
    3. Update validation rule condition

    Edge Cases & Variations

    1. Bulk API behaves same as UI
    2. Managed rules cannot be bypassed

    Common Mistakes to Avoid

    1. Disabling rules permanently
    2. Using profile-based checks

    You’re modifying setup and non-setup objects in the same transaction. Problem Explanation Salesforce separates setup objects (User, Profile) from standard objects to maintain system integrity.

    You’re modifying setup and non-setup objects in the same transaction.

    Problem Explanation

    Salesforce separates setup objects (User, Profile) from standard objects to maintain system integrity.

    Root Cause(s)

    1. Creating Users and Accounts together
    2. Updating Permission Sets alongside data records
    3. Test setup not isolated

    Step-by-Step Solution

    1. Move setup object DML to System.runAs()
    2. Separate transactions using @testSetup
    3. Use async Apex for one side if required

    Edge Cases & Variations

    1. Permission Set Assignments count as setup DML
    2. Community Users increase complexity

    Common Mistakes to Avoid

    1. Creating users inside main test method
    2. Ignoring setup vs non-setup distinction

    The JavaScript tries to access data before the wire or API response is available. Problem Explanation LWCs render before async data arrives.

    The JavaScript tries to access data before the wire or API response is available.

    Problem Explanation

    LWCs render before async data arrives. Accessing nested fields without checks causes runtime errors.

    Root Cause(s)

    1. Missing null checks
    2. Incorrect API response shape
    3. Wire method not returning expected fields

    Step-by-Step Solution

    1. Use optional chaining (?.)
    2. Guard rendering with if:true
    3. Log the response structure in wiredResult

    CODE SNIPPET:
    get accountName() {
    return this.accountData?.Name;
    }

    Edge Cases & Variations

    1. Imperative Apex calls need manual loading states

    2. Cacheable Apex may return stale data

    Common Mistakes to Avoid

    1. Assuming data exists on first render
    2. Accessing nested objects blindly
