質問 # 15
Given the method below:
public function FriendlyGreeting (name: String): String {
if (name == null or name.length == 0) throw " Requires a non-empty string! " return " Hello, " + name + " ! "
}
What best practice is violated in the code?
正解:D
解説:
Standardization and readability are critical components of Gosu Syntax and development within Guidewire.
The language follows specific naming conventions that align with common object-oriented practices (similar to Java or C#). According to the InsuranceSuite Developer Fundamentals, method names and variable names must follow lowerCamelCase. This means they should begin with a lowercase letter, and each subsequent concatenated word should begin with an uppercase letter.
In the provided , the method is named FriendlyGreeting. Because it begins with an uppercase " F " , it violates the naming convention for methods and could be easily mistaken for a Class or Type constructor, which should follow UpperCamelCase (also known as PascalCase). Correcting this to friendlyGreeting ensures that the code is consistent with the rest of the out-of-the-box (OOTB) Guidewire codebase and follows the Gosu Coding Standards.
Regarding the other options: A is incorrect because the return statement is validly returning a single concatenated String. B is incorrect because throwing exceptions is a standard way to handle unexpected data or state errors in Gosu logic. C is incorrect because a method is not required to have a catch block for a throw statement; the exception is intended to be propagated up the call stack to a handler or the system ' s top-level error management. Therefore, the naming convention violation in Option D is the primary best practice issue identified in the snippet.
質問 # 16
A user needs to enter a Tax ID into a field, and the application should provide feedback if the entered value does not match a specific format (e.g., nn-nnnnnnn). Which validation techniques are best practices for implementing this configuration? (Choose 2)
正解:C、E
解説:
Guidewire InsuranceSuite emphasizes " immediate feedback " to improve the user experience and maintain data quality. For structural validation-where data must follow a very specific pattern like a Tax ID (nn- nnnnnnn)-the two most effective tools are the inputMask and regex (or validationExpression) properties.
An inputMask (Option D) is the primary best practice for this requirement. It provides a visual template within the text box (e.g., ##-#######), guiding the user on the exact number of characters required and automatically inserting non-numeric characters like hyphens. This prevents the user from entering malformed data in the first place, acting as a proactive constraint. It is significantly more user-friendly than allowing a user to type freely and only showing an error after they attempt to save the page.
However, an input mask alone may not catch all logical errors. Using a regex property or a validationExpression (Option A) allows the developer to define a regular expression that the input must satisfy. If the user enters a value that doesn ' t match the pattern, the PCF engine generates an immediate validation error on the screen. This " field-level validation " happens on the client side or during the UI request-response cycle, rather than waiting for a database transaction.
Using a Pre-Update rule (Option B) is considered a " late " validation. While it ensures data integrity at the database level, it provides a poor user experience because the user only discovers the error after clicking " Update " and potentially losing their context. Therefore, the combination of a mask to guide entry and a regex to verify the pattern is the verified standard for PCF Configuration.
質問 # 17
What are two types of Guidewire Profiler? (Select two)
正解:B、D
解説:
The Guidewire Profiler is the primary tool used by developers to diagnose performance issues in InsuranceSuite. It functions by instrumenting " stacks " of code execution and reporting the time spent in various operations like database queries or Gosu rules. According to the System Health and Quality documentation, the Profiler is categorized by how it is triggered and what it monitors.
The Web Profiler (Option A) is used to analyze performance within the user interface. When enabled, it captures the execution of a single web request (a page load or a button click), allowing the developer to see exactly which PCF widgets or page-level Gosu expressions are causing latency.
The Entry-point Profiler (Option D) is a broader category that includes profiling for non-UI operations. Entry points are the " doors " through which the application begins a task. Common entry points that can be profiled include Batch Processes, Work Queue Executors, and Web Services (API calls). By selecting an entry-point profiler, a developer can monitor the performance of background jobs or external integrations that do not have a direct UI component.
Options like Database Performance (Option B) are not specific types of the Profiler itself, but rather outcomes or areas of analysis that the profiler provides. Exit-point (Option C) and Worksheet (Option E) are not recognized classifications of the profiling tool in the Guidewire developer curriculum. Understanding these two types allows developers to strategically apply performance monitoring across the entire application stack.
質問 # 18
Given this function:
929 public function checkConnection() {
930 try
931 {
932 var conn = DriverManager.getConnection(url)
933 // logic here
934 }
935 catch (e : Exception)
936 {
937 // handle exception
938 }
939 }
What action will align the function with Gosu best practices?
正解:A
解説:
The Guidewire InsuranceSuite Developer Fundamentals course emphasizes the importance of a consistent coding style to ensure that configuration code is readable and maintainable. This consistency is enforced through the Gosu Style Guide, which dictates specific rules for formatting and indentation that all Guidewire developers should follow.
One of the most foundational rules in the Gosu Style Guide concerns the placement of curly braces ({). In Gosu, as in many modern programming languages derived from C-style syntax, there are two primary styles of brace placement: " Expanded " (where the brace is on its own line) and " K & R " or " 1TBS " (where the brace is on the same line as the statement). Guidewire strictly adheres to the practice of placing the opening curly brace at the end of the line that begins the block (the " 1TBS " style).
Therefore, in the provided :
* The brace on line 931 should be moved to the end of line 930 (try {).
* The brace on line 936 should be moved to the end of line 935 (catch (e : Exception) {).
Adhering to this style is more than just a preference; it is a requirement for passing Quality Gates in a Guidewire Cloud environment. When code is pushed to a repository in Guidewire Cloud, automated inspections check for these formatting issues. Code that fails these style checks may be flagged as technical debt or even prevent a successful build if strict quality gates are enabled. By moving the braces to the end of the previous lines (Option A), the developer ensures the code matches the visual pattern of the base Guidewire application, making it easier for other team members and Guidewire support to review and maintain the code over time.
質問 # 19
A developer needs to create a new entity for renters that contains a field for the employment status.
EmploymentStatusType is an existing typelist. How can the entity and new field be created to fulfill the requirement and follow best practices?
正解:B
解説:
When extending the Guidewire Data Model with a brand-new concept-in this case, a "Renter"-developers must adhere to specific naming and architectural standards. Because the "Renter" entity does not exist in the base product, it must be created as a new entity definition.
According to Guidewire best practices for new entities, the file must be created with the.eti (Entity Interface) extension and placed in the Extensions -> Entity folder. Furthermore, to ensure "Upgrade-Safety" and avoid collisions with future Guidewire product updates, the entity name must include the_Extsuffix. Therefore, the file should be named Renter_Ext.eti (Option D).
Within this new entity, the developer needs to reference the existing EmploymentStatusType typelist. In Guidewire, a field that links to a typelist is defined as atypekey. Since the field name itself is specific to this new custom entity, the field name EmploymentStatus is appropriate. It is important to note that while some older practices suggested suffixing thecolumn namewith _Ext, the primary mandatory best practice for cloud- ready development focuses on theEntity nameandTypelist namesuffixes.
Other options are incorrect for the following reasons:
* Option A:Uses .etx, which is for extending anexistingbase entity, not creating a new one.
* Option B:Uses a .etl extension, which is not a valid Guidewire metadata extension for entity definition.
* Option C:Suggests modifying the typelist logic (adding a code "Renter") which does not address the need to create a new "Renter" entity with an employment field. Option D represents the most complete and architecturally sound approach to meeting the business requirement.
