Route table check tool¶
The route table check tool checks whether the route parameters returned by a router match what is expected. The tool can also be used to check whether a path redirect, path rewrite, or host rewrite match what is expected.
- router_check_tool [-t <string>] [-c <string>] [-d] [-p] [–] [–version] [-h] <unlabelledConfigStrings>
- -t <string>, –test-path <string>
Path to a tool config JSON file. The tool config JSON file schema is found in config. The tool config input file specifies urls (composed of authorities and paths) and expected route parameter values. Additional parameters such as additional headers are optional.
Schema: All internal schemas in the tool are based on proto3.
- -c <string>, –config-path <string>
Path to a v2 router config file (YAML or JSON). The router config file schema is found in config and the config file extension must reflect its file type (for instance, .json for JSON and .yaml for YAML).
- -d, –details
Show detailed test execution results. The first line indicates the test name.
Displays test results for failed tests. Omits test names for passing tests if the details flag is set.
- -f, --fail-under
Represents a percent value for route test coverage under which the run should fail.
Enables comprehensive code coverage percent calculation taking into account all the possible asserts. Displays missing tests.
Disables the deprecation check for RouteConfiguration proto.
- -h, –help
Displays usage information and exits.
The program exits with status EXIT_FAILURE if any test case does not match the expected route parameter value.
If a test fails, details of the failed test cases are printed if
--detailsflag is provided. The first field is the expected route parameter value. The second field is the actual route parameter value. The third field indicates the parameter that is compared. In the following example, Test_2 and Test_5 failed while the other tests passed. In the failed test cases, conflict details are printed.
Test_1 Test_2 default other virtual_host_name Test_3 Test_4 Test_5 locations ats cluster_name Test_6
The tool can be built locally using Bazel.
bazel build //test/tools/router_check:router_check_tool
bazel-bin/test/tools/router_check/router_check_tool -c router_config.(yaml|json) -t tool_config.json --details
A bash shell script test can be run with bazel. The test compares routes using different router and tool configuration files. The configuration files can be found in test/tools/router_check/test/config/… .
bazel test //test/tools/router_check/...
