## Walkthrough
A new abstract entity `AssessmentEvent` was added to model common assessment event properties. A concrete `LetterSoundAssessmentEvent` entity was introduced for letter-sound assessments, with corresponding database table and foreign key. DAO interfaces and implementations were added for data access. The student analytics controller and JSP views were updated to include letter sound event data and visualizations. A new CSV export controller for letter sound assessment events was introduced. Selenium UI tests and page objects for student analytics were added. The main artifact version was incremented from 2.6.15-SNAPSHOT to 2.6.16-SNAPSHOT.

20-22: Consider using LocalDateTime instead of Calendar.While
Calendarworks, it's considered legacy. Modern JPA applications should useLocalDateTimefrom thejava.timepackage for better API design and thread safety.- @NotNull - @Temporal(TemporalType.TIMESTAMP) - private Calendar timestamp; + @NotNull + private LocalDateTime timestamp;And update the import:
-import java.util.Calendar; +import java.time.LocalDateTime;
24-28: LGTM: Well-documented Android ID field.The field is properly validated and the documentation reference to Android developer docs is helpful. Consider adding
@Column(length = 64)if you want to enforce the typical Android ID length constraint at the database level.
42-51: LGTM: Flexible additional data storage with good documentation.The field design provides good flexibility for storing event-specific data. The example in the javadoc is helpful for developers.
For future consideration: If you're using a modern database that supports JSON types (PostgreSQL, MySQL 5.7+), you might consider using
@JdbcType(JsonType.class)for better type safety and query capabilities.

Filter events by student to maintain consistency with controller purpose.
The current implementation fetches all letter sound assessment events without filtering by the specific student. This is inconsistent with the controller's purpose (handling requests for a specific student) and differs from how the student data is retrieved.
Apply this diff to filter events by the student's Android ID:
-List<LetterSoundAssessmentEvent> letterSoundAssessmentEvents = letterSoundAssessmentEventDao.readAll();
+List<LetterSoundAssessmentEvent> letterSoundAssessmentEvents = letterSoundAssessmentEventDao.readAllByAndroidId(student.getAndroidId());Note: This assumes the DAO has or will implement a readAllByAndroidId method. If not available, you'll need to add this method to the DAO interface and implementation.

🛠️ Refactor suggestion
Add chart data preparation for consistency with other event types.
The letter sound assessment events are added to the model without any chart data preparation, unlike the other event types (Word, StoryBook, Video) which all have extensive chart preparation logic. This inconsistency suggests the implementation is incomplete.
Consider adding chart data preparation similar to other event types:
+// Prepare chart data - LetterSoundAssessmentEvents
List<LetterSoundAssessmentEvent> letterSoundAssessmentEvents = letterSoundAssessmentEventDao.readAll();
+List<String> letterSoundMonthList = new ArrayList<>();
+List<Integer> letterSoundEventCountList = new ArrayList<>();
+if (!letterSoundAssessmentEvents.isEmpty()) {
+ // Group event count by month (e.g. "Aug-2024", "Sep-2024")
+ Map<String, Integer> eventCountByMonthMap = new HashMap<>();
+ SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMM-yyyy");
+ for (LetterSoundAssessmentEvent event : letterSoundAssessmentEvents) {
+ String eventMonth = simpleDateFormat.format(event.getTimestamp().getTime());
+ eventCountByMonthMap.put(eventMonth, eventCountByMonthMap.getOrDefault(eventMonth, 0) + 1);
+ }
+
+ // Iterate each month from 4 years ago until now
+ Calendar calendar4YearsAgo = Calendar.getInstance();
+ calendar4YearsAgo.add(Calendar.YEAR, -4);
+ Calendar calendarNow = Calendar.getInstance();
+ Calendar month = calendar4YearsAgo;
+ while (!month.after(calendarNow)) {
+ String monthAsString = simpleDateFormat.format(month.getTime());

+
+ letterSoundEventCountList.add(eventCountByMonthMap.getOrDefault(monthAsString, 0));
+

Spring to recognize it as a bean for dependency injection. Add the @Repository

Consider adding explicit wait and error handling for better test stability.
The current implementation will throw a generic NoSuchElementException if the element is not found. Consider using explicit waits and providing more context:
+import org.openqa.selenium.support.ui.WebDriverWait;
+import org.openqa.selenium.support.ui.ExpectedConditions;
+import java.time.Duration;
public class StudentPage {
private WebDriver driver;
+ private WebElement studentPageElement;
public StudentPage(WebDriver driver) {
this.driver = driver;
- driver.findElement(By.id("studentPage"));
+ WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
+ this.studentPageElement = wait.until(
+ ExpectedConditions.presenceOfElementLocated(By.id("studentPage"))

14, the constructor directly calls driver.findElement without waiting, which can
cause a NoSuchElementException if the element is not immediately present. To fix
this, replace the direct findElement call with an explicit wait using
WebDriverWait to wait for the element with id "studentPage" to be visible or
present. Also, add error handling to catch timeout exceptions and provide a
clear, contextual error message to improve test stability and debugging.

23 to 28, the method pressRandomStudent does not check if the list of student
links is empty before accessing a random index, which can cause an
IndexOutOfBoundsException. Add a check to verify that the list is not empty
before selecting and clicking a random link; if the list is empty, handle it
gracefully, such as by logging a warning or skipping the click action.

Add assertions to verify test behavior.
The test method navigates through the pages but doesn't include any assertions to verify the expected behavior. Consider adding assertions to make the test more robust:
@Test

log.info("testRandomStudentEditPage");
StudentListPage studentListPage = new StudentListPage(driver);
+ String listPageUrl = driver.getCurrentUrl();
studentListPage.pressRandomStudent();
log.info("driver.getCurrentUrl(): " + driver.getCurrentUrl());

+ // Verify navigation occurred
+ assertNotEquals(listPageUrl, driver.getCurrentUrl(),
+ "URL should change after clicking a student");
+ assertTrue(driver.getCurrentUrl().contains("/analytics/students/"),
+ "URL should contain student detail path");
StudentPage studentPage = new StudentPage(driver);

to check that the current URL after pressing a random student is not null or

Import the necessary assertion methods from JUnit such as assertNotEquals and
