Salesforce PDI Actual Questions

• By providing device-awareness for mobile and desktops. This is true because the Lightning Component framework is a UI framework for developing Lightning components for mobile and desktop devices. Lightning web components and Aura components can coexist and interoperate on a page. The framework takes care of rendering the components appropriately for different devices and screen sizes1.
• By providing an Agile process with default steps. This is false because the Lightning Component framework does not provide any specific process or methodology for developing solutions. Developers can use any process that suits their needs, such as Agile, Waterfall, or Scrum2.
• By providing code review standards and processes. This is false because the Lightning Component framework does not provide any code review standards or processes. Developers are responsible for ensuring the quality and maintainability of their code, and they can use tools such as code analysis, testing, and debugging to help them3.
• By providing change history and version control. This is false because the Lightning Component framework does not provide any change history or version control features. Developers can use tools such as Git, SVN, or Salesforce DX to manage their source code and track changes.

The code should be altered to collect the insert method return value as a SaveResult variable, which can provide information about the success or failure of the insert operation, as well as any errors that occurred. The SaveResult variable can be used to print the error messages or debug logs, or to perform conditional logic based on the outcome of the insert operation. For example, the code can be modified as follows:

Account a = new Account(Name = ‘A’); SaveResult sr = Database.insert(a, false); if (sr.isSuccess()) { System.debug(‘Account inserted successfully’); } else { System.debug('Account insertion failed: ’ + sr.getErrors()[0].getMessage()); }

The second parameter of the Database.insert method is the allOrNone option, which specifies whether to roll back the entire transaction or not if any record fails to insert. Setting it to true or false does not affect the debugging of the issue, but only the behavior of the transaction. Adding a System.debug() statement before the insert method does not help to debug the issue, because it does not provide any information about the insert operation itself. Adding a try/catch around the insert method can help to handle any exceptions that may occur during the insert operation, but it does not provide the same level of detail as the SaveResult variable.

The deployment passes because the Apex code has the required 75% code coverage. In Salesforce, you need at least 75% of your Apex code to be covered by unit tests, and all of those tests must complete successfully. When deploying to a production environment, every unit test in your organization namespace is executed. Since the developer’s test method covers 81% of the Apex code, it meets the minimum requirement for deployment.

Option A is incorrect because the Apex trigger has code coverage, as it is invoked by the test method that calls MyClass.myStaticMethod. The trigger and the method have the same logic, so the test method effectively tests both.

Option B is incorrect because assertions are not mandatory for deployment, although they are highly recommended for verifying the expected outcomes of the test cases. Assertions are statements that compare the actual results of the test with the expected results. If an assertion fails, the test fails.

Option D is incorrect because including both classes and the trigger in the deployment is not sufficient to ensure code coverage. The developer still needs to write and run unit tests that cover the Apex code.

When multiple triggers are associated to the same object and event, such as before insert or after update, the trigger execution order cannot be guaranteed by Salesforce1. This means that the triggers may run in any order, and the order may change from one execution to another. Therefore, it is not advisable to rely on the order of execution of triggers, or to assume that the order is based on the trigger name, creation date, or modification date. Instead, it is recommended to use a single trigger per object and event, and use helper classes or methods to handle the logic for different scenarios2. References:
