Testing Framework

The usage of the testing framework requires a user to:

1. write a test file, an example can be found in test/runner/basic_scan.test.

# description: Basic scan test

-INPUT dataset/tinysnb/
-PARALLELISM 1

-NAME SimpleMatchTest
-QUERY MATCH (a:person)
---- 7

One test file is expected to hold a test suite, including a configuration of graph (csv files) input dir (-INPUT), parallelism of the processor (-PARALLELISM), and also one or multiple queries.
Each query consists of a name, -NAME, and the cypher -QUERY, followed by the number of tuples, e.g., ---- 1.
Comparison on the query result is not supported for now (will be added in a later version).

2. add test file into the unittest's data dependency

filegroup(
    name = "testfiles",
    srcs = [
        "basic_extend.test",
        "basic_hash_join.test",
        "basic_scan.test",
    ],
    visibility = ["//visibility:public"],
)

To read these files in bazel test system, we need add them as data dependency, so they can be exposed and read in the bazel sandbox.

3. create a unittest

TEST(BasicTest, BasicScan) {
    TestHelper testHelper;
    ASSERT_TRUE(testHelper.runTest("test/runner/basic_scan.test"));
}

To use the test in unittest, we need add a unittest function to specify the path of the test file.
