Description
Summary
datarow mismatch tells me that some indices have mismatches in data. This message is precise, but not very clear (to me).
Background and Motivation
[TestMethod]
[DataRow("Luxury Car", "Alice Johnson", 1500, "https://example.com/luxurycar.jpg", "https://example.com/luxurycar")]
[DataRow("Luxury Car", "Alice Johnson", 1500.00, "https://example.com/luxurycar.jpg", "https://example.com/luxurycar")]
[DataRow("Diamond Ring", "Bob Brown", 2000.00, "https://example.com/diamondring.jpg", "https://example.com/diamondring")]
public void AddGift_ShouldRejectExpensiveGifts(string name, string reservedBy, decimal price, string imageUrl, string link)
{
// Arrange
var gift = new Gift(name, reservedBy, price, imageUrl, link);
// Act & Assert
Assert.ThrowsException<ArgumentException>(() => Program.AddGift(gift), "Gift price cannot exceed $1,000.");
}The warning is very precise, and probably wants to show me that there is error in the second parameter in the attribute, and also in the second parameter in the signature, but to me it reads as (x,y) coordinates and the error is not obvious to me, especially since double and decimal are both numbers.
Proposed Feature
Reword the warning to say: DataRow argument types do not match method parameter types. Parameter price expects decimal type, but the provided value has type double. (and the same for other mismatches... Parameter imageUrl expects string, but the provided value has type int.)
