Learning to use Google Test

After configuring VS, write the first Demo.

 

1: // gTest. cpp: defines the entry point of the console application.
2 ://
3:
4: # include "stdafx. h"
5:
6: int Foo (int a, int B)
7 :{
8: if (a = 0 | B = 0)
9 :{
10: throw "don't do that ";
11 :}
12: int c = a % B;
13: if (c = 0)
14: return B;
15: return Foo (B, c );
16 :}
17:
18: int Add (int a, int B)
19 :{
20: return a + B;
21 :}
22:
23: # include <gtest/gtest. h>
24:
25: TEST (FooTest, HandleNoneZeroInput)
26 :{
27: EXPECT_EQ (2, Foo (4, 10 ));
28: EXPECT_EQ (6, Foo (30, 18 ));
29: // ASSERT_EQ (3, Foo (3, 6 ));
30: // ASSERT_EQ (3, Foo (3, 7 ));
31: // EXPECT_EQ (3, Foo (5, 7 ));
32 :}
33:
34: TEST (AddTest, HandleNoneZeroInput)
35 :{
36: EXPECT_EQ (2, Add (1, 1 ));
37: // EXPECT_EQ (2, Add (1, 2 ));
38 :}
39:
40: int _ tmain (int argc, _ TCHAR * argv [])
41 :{
42: testing: InitGoogleTest (& argc, argv );
43: return RUN_ALL_TESTS ();
