    String invalidSObjectError = System.Label.invalid_Sobject_Name;
    String invalidFieldError = System.Label.Invalid_Sobject_Field;

    }

    for (String field : fields.keySet()) {
        try {
            newObject.put(field, fields.get(field));
        } catch (SObjectException ex) {
            throw new InvalidTypeNameException(invalidFieldError);
        }
    }

    insert newObject;
    return newObject;
}

public class InvalidTypeNameException extends Exception {
}

}

@IsTest 公共共享类 SobjectByParamsTest {

SobjectByParams sobjectByParams;

private static final String TestName = 'TestName';
private static final String BCity = 'Lviv';
private static final String LastName = 'Kapo';
private static final String Email = 'pavlofff33@gmail.com';

@IsTest
static void createSObject() {
    SobjectByParams sobjectByParams = new SobjectByParams();
    Map<String, String> fields = new Map<String, String>();
    fields.put('BillingCity', BCity);
    Test.startTest();
    SObject result = sobjectByParams.createSObject(TestName, fields);
    Test.stopTest();
    System.assertEquals(BCity, result.get(BCity));
}

}

SobjectByParams.InvalidTypeNameException：invalidSobjectNameError - 问题

测试工作在 53.33% 但我需要至少 80%

我不知道如何解决我的问题

【解决方案1】：

TestName 不应该是像 Contact 这样的 sObject 名称吗？当您正常运行这段代码时，它是否有效，它是否插入任何东西或抛出？检查/修复它，然后您可能也需要进行阴性测试。

做第二个测试方法

@isTest
static void testPassingBadData() {
    SobjectByParams sobjectByParams = new SobjectByParams();
    Map<String, String> fields = new Map<String, String>();
    fields.put('BillingCity', BCity);
    try{
        sobjectByParams.createSObject('NoSuchObjectInTheSystem', fields);
        System.assert(false, 'This should have failed and thrown exception');
    } catch(Exception e){
        System.assert(e.getMessage().contains(Label.Invalid_Sobject_Field));
    }
}
