namespace Synergex.TestFramework public static class Assert
The Synergex.TestFramework.Assert class includes methods you can use to test various conditions in unit tests for traditional Synergy projects. If the condition being tested by an Assert method call is not met, an exception is thrown (Synergex.TestFramework.AssertFailedException or Synergex.TestFramework.AssertInconclusiveException). The Synergex.TestFramework.Assert class is modeled after Microsoft’s Assert class (see learn.microsoft.com/en-us/dotnet/api/microsoft.visualstudio.testtools.unittesting.assert), but there are differences. Note the following:
- Numeric comparisons are type agnostic, so logical types are equal regardless of the actual type of the value. For example, an i1 value of 4 is treated as equal to a d4 value of 4.
- If an assertion fails, a message is displayed in the unit test results. Most Assert methods have at least one overload that includes a message parameter, which enables you to specify what the failure message will be (this overrides the default failure message). Additionally, you can use String.Format parameters to insert the value of an object, variable, or expression into message by using the parameters parameter, which is available for all method overloads that have message (see learn.microsoft.com/en-us/dotnet/api/system.string.format). For example, the following statement results in the message “Message takes 4 arguments [2,3]. Fourth” if string1 is not equal to string2.
Assert.AreEqual(string1, string2, "Message takes {0} arguments [{1},{2}]. {3,10}", 4, 2, 3, "fourth")

Methods
AreEqual
public static AreEqual(expectedObj, actualObj)public static AreEqual(expectedObj, actualObj, message[, parameters]) public static AreEqual(expectedNum, actualNum)public static AreEqual(expectedNum, actualNum, delta)public static AreEqual(expectedNum, actualNum, delta, message[, parameters])public static AreEqual(expectedStr, actualStr, ignoreCase)public static AreEqual(expectedStr, actualStr, ignoreCase, message[, parameters])
Tests whether the specified objects, numbers, or strings are equal or whether specified numbers are within an allowed difference (delta) of each other. An exception is thrown if the test fails—i.e., if they are not equal or within the allowed difference. If the test fails, a message is displayed in the test results. If message is passed, that string is used for the failure message.
The object, numeric value, or string that the test expects. (@Object, n, System.String)
The object, numeric value, or string that the tested code produces. (@Object, n, System.String)
A string that is displayed in unit test results if the assertion fails. If message is null or empty, a default message is used (for example, “Objects are not equal”). (System.String)
String.Format parameters that enable you to insert the value of an object, variable, or expression into message. See the introductory discussion for the Assert class above for more information. ([#]@Object)
A numeric value specifying the required accuracy of a numeric comparison (i.e., an allowed difference between expectedNum and actualNum). For example, if delta is 2, the values 8 and 6 are considered equal, but 8 and 5 are not. If delta is 0, the test succeeds only if the values are equal. (n)
A Boolean value specifying case-insensitive (true) or case-sensitive (false) comparison. (boolean)

public static AreNotEqual(notExpectedStr, actualStr, ignorecase)
public static AreNotEqual(notExpectedStr, actualStr, ignorecase, message[, parameters])
Tests whether the specified objects, numbers, or strings are not equal or whether specified numbers are not within an allowed difference (delta) of each other. An exception is thrown if the test fails—i.e., if they are equal or within the allowed difference. If the test fails, a message is displayed in the test results. If message is passed, that string is used for the failure message.
The object, numeric value, or string that is expected to be different than actualObj, actualNum, or actualStr. (@Object, n, System.String)
The object, numeric value, or string that the tested code produces. (@Object, n, System.String)
A message that is displayed in unit test results if the test fails. If message is null or empty, a default message is used. (System.String)

A numeric value specifying the required accuracy (i.e., an allowed difference) between notExpectedNum and actualNum. For example, if delta is 2, the values 8 and 6 are considered equal, but 8 and 5 are not. If delta is 0, the test succeeds only if the values are equal. (n)
A Boolean value specifying case-insensitive (true) or case-sensitive (false) comparison. (boolean)
AreNotSame
public static AreNotSame(notExpectedObj, actualObj)
public static AreNotSame(notExpectedObj, actualObj, message[, parameters])
Tests whether the specified object variables refer to different objects. If they refer to the same object, the test fails. If the test fails, an exception is thrown and a message is displayed in the test results. If message is passed, that string is used for the failure message.
The object that is expected to be different than actualObj. (@Object)
The object that the tested code produces. (@Object)

AreSame
public static AreSame(expectedObj, actualObj)
public static AreSame(expectedObj, actualObj, message[, parameters])
Tests whether the specified object variables refer to the same object. The assertion fails if they refer to different objects. If the assertion fails, an exception is thrown and a message is displayed in the test results. If message is passed, that string is used for the failure message.
