Batch Apex is designed for handling large-scale operations that involve processing thousands or even millions of records—tasks that would normally exceed Salesforce’s standard execution limits. By dividing data into smaller sets, or batches , this approach allows processing to occur asynchronously, helping you stay within platform limits. If your use case involves actions like data cleanup, mass updates, or archiving, Batch Apex is often the most efficient choice. When writing tests for Batch Apex, only a single execution of the execute method can be directly tested. To manage system resources effectively and avoid governor limit issues, you can specify the scope parameter in the executeBatch method, which controls how many records are processed at a time. The executeBatch call runs asynchronously, meaning the process continues in the background after it starts. Therefore, during testing, it’s essential to ensure that the batch process completes before verifying the results....
