请告诉我如何写一个顶点测试

Question

我有一个映射，其中键是月份的日期，值是月份的名称，并且有两个方法以及一个包装器类:

在getMonths方法中，我从输入参数中获取值，然后使用这些值填充地图。

在getExpensesByFilters方法中，我需要通过选项输入值

public static Map<Integer, String> monthNumbers = new Map<Integer, String>{
1 => 'January',
2 => 'February',
3 => 'March',
4 => 'April',
5 => 'May',
6 => 'June',
7 => 'July',
8 => 'August',
9 => 'September',
10 => 'October',
11 => 'November',
12 => 'December'
};

// передаем Id keeper чтоб достать значения 
public static String getMonths(Integer currentYear, Id keeper) {
Integer year = currentYear;
// AND calendar_month(MonthDate__c) =: month
// Integer month = 10;
List<AggregateResult> aggregateResultList = [
SELECT calendar_month(MonthDate__c) month, SUM(SpentAmount__c) amount, SUM(Balance__c) balance, SUM(Income__c) income
FROM Month_Expense_Application__c
WHERE calendar_year(MonthDate__c) =: year AND Keeper__c =: keeper
GROUP BY calendar_month(MonthDate__c)
ORDER BY calendar_month(MonthDate__c)
];

Map<Integer, MonthRow> months = new Map<Integer, MonthRow>(); // key = number of month 
for (AggregateResult result : aggregateResultList) {
MonthRow row = new MonthRow();
row.monthName = monthNumbers.get((Integer)result.get('month'));
row.amount = (Decimal)result.get('amount');
row.monthNumber = (Integer)result.get('month');
row.income = (Decimal)result.get('income');
row.balance = (Decimal)result.get('income') - (Decimal)result.get('amount');
months.put((Integer)result.get('month'), row);
}

List<MonthRow> result = new List<MonthRow>();
for (Integer i = 1; i < 13; i++) {
if (!months.containsKey(i)) {
MonthRow row = new MonthRow();
row.monthName = monthNumbers.get(i);
row.amount = 0;
row.monthNumber = i;
row.income = 0;
//months.put(i, row);
result.add(row);
} else {
result.add(months.get(i));
}
}
return JSON.serialize(result);
//return JSON.serialize(months.values());
}

if (monthNumbers.get(key) == monthString) {

}

expensesMap.get(fullDate).add(a);
} else {
List<ExpenseCard__c> expenses = new List<ExpenseCard__c>();
expenses.add(a);
expensesMap.put(fullDate, expenses);
}
}
System.debug(expensesMap);
return expensesMap;

}
public class MonthRow {
public Integer monthNumber{get; set;}
public String monthName{get; set;}
public Decimal amount{get; set;}
public Decimal income{get; set;}
public Decimal balance{get; set;}
}

我不知道如何为这些方法写测试，你能告诉我怎么做吗?

祝你一切顺利。像这样的getMonth方法呢?

@TestSetup
private static void setup() {
MAKEKEEPER
}
@IsTest
private static void testGetMonths() {
Integer yearToCheck = 2022;
String keeperId = [SELECT Id FROM Keeper__c].Id;
List<Month_Expense_Application__c> expenses = new List<Month_Expense_Application__c>();
for(Integer key: YOURCLASS.monthNumbers.keySet()) {
for (Integer day = 3; day < 6; day++) {
expenses.add(new Month_Expense_Application__c(
MonthDate__c = Date.newinstance(yearToCheck, key, 17),
SpentAmount__c = key,
Balance__c = key, 
Income__c = key,
Keeper__c = keeperId
));
}
}
String jsonResult;
Test.startTest();
jsonResult = YOURCLASS.getMonths(yearToCheck, keeperId);
Test.stopTest();

List<YOURCLASS.MonthRow> result = (List<YOURCLASS.MonthRow>)JSON.deserialize(jsonResult, List<YOURCLASS.MonthRow>);
for(YOURCLASS.MonthRow resultRow: result) {
System.assertEquals(YOURCLASS.monthNumbers.get(resultRow.monthNumber), resultRow.monthName);
System.assertEquals(resultRow.monthNumber * 3, resultRow.balance);
System.assertEquals(resultRow.monthNumber * 3, resultRow.income);
System.assertEquals(resultRow.monthNumber * 3, resultRow.amount);
}
}
