Console stuck on 0% Code Coverage
I am running up against a bug when testing the code provided in Trailhead "Getting Started with Apex Unit Tests". I was working on the "VerifyDate" test and could not achieve any coverage. So I copied the example "TemperatureConverter" and "TemperatureConverterTest". That test also showed 0% coverage. Anyone having the same issue?
Example:
public class TemperatureConverter {
// Takes a Fahrenheit temperature and returns the Celsius equivalent.
public static Decimal FahrenheitToCelsius(Decimal fh) {
Decimal cs = (fh - 32) * 5/9;
return cs.setScale(2);
}
}
Example Test:
@isTest
private class TemperatureConverterTest {
@isTest static void testWarmTemp() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(70);
System.assertEquals(21.11,celsius);
}
@isTest static void testFreezingPoint() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(32);
System.assertEquals(0,celsius);
}
@isTest static void testBoilingPoint() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(212);
System.assertEquals(100,celsius,'Boiling point temperature is not expected.');
}
@isTest static void testNegativeTemp() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(-10);
System.assertEquals(-23.33,celsius);
}
}
Example:
public class TemperatureConverter {
// Takes a Fahrenheit temperature and returns the Celsius equivalent.
public static Decimal FahrenheitToCelsius(Decimal fh) {
Decimal cs = (fh - 32) * 5/9;
return cs.setScale(2);
}
}
Example Test:
@isTest
private class TemperatureConverterTest {
@isTest static void testWarmTemp() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(70);
System.assertEquals(21.11,celsius);
}
@isTest static void testFreezingPoint() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(32);
System.assertEquals(0,celsius);
}
@isTest static void testBoilingPoint() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(212);
System.assertEquals(100,celsius,'Boiling point temperature is not expected.');
}
@isTest static void testNegativeTemp() {
Decimal celsius = TemperatureConverter.FahrenheitToCelsius(-10);
System.assertEquals(-23.33,celsius);
}
}
Amit is right you should get 100 % coverage .Please go to test class and click on RunTest Button and click on class link and check .
Thank you. Here is a screen of my test. It ran successfully, but still shows 0% coverage. I doublechecked on the class tab as well at the top.
