Google Test example of use for conan.io

Conan GTest Example

Getting Started

• Download conan client from Conan.io.

• Run the following command.

conan create . user/channel

The above command will export, build and test a conan package for a custom encryption library.

Synopsis

Conan.io example for gtest project.

The project is using OpenSSL to build an encryption library, and using Google test to ensure that the library is built correctly. The Google test library is required in the test_package/conanfile.py.

A different approach would be running the test at the end of the build() method in the root conanfile.py and require gtest library as a build_require, so it would be only downloaded when the encryption library has to be built from sources.

With that approach, the test_package project could just run an example using/linking with the encryption library.

Clion support

Hello,

when I run the command
conan install . -s build_type=Debug --install-folder=cmake-build-debug --build outdated
the test code is still not available in CLion. Can you please add an example of how to integrate the GTest in CLion via conan as well?

Thank you

Test failed.

Example is incorrect

This example appears to be a test for OpenSSL rather than Googletest.

Example doesn't work

Step by step instructions fail at first step:

ERROR: Invalid parameter 'lasote', specify the full reference or user/channel

Dynamic libraries aren't found at runtime

Building this example works great on my system (OS X 10.11.3, make 3.4.3), but running the resulting builds fail with the following error:
$ ./bin/encryption_test dyld: Library not loaded: libssl.1.0.0.dylib Referenced from: [redacted]./bin/encryption_test Reason: image not found Trace/BPT trap: 5

Switching to static libraries works :)

undefined reference to `testing::internal::GetBoolAssertionFailureMessage`

I'm new to conan. This project is mentioned as an example for using Google Test with conan. I try to use EXPECT_FALSE, but if I add EXPECT_FALSE(false); in line 46 of encryption_test.cpp I get an unexpected error:

/path/to/conan-gtest-example/test/encryption_test.cpp:46: undefined reference to `testing::internal::GetBoolAssertionFailureMessage[abi:cxx11](testing::AssertionResult const&, char const*, char const*, char const*)'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I installed dependencies like this

conan install -s compiler=clang -s compiler.version=3.8 -s compiler.libcxx=libstdc++ --build=missing
