Codacy Plugins Test

Provide a testing interface for the external docker tools.

Test definition

The test files should be placed in /docs/tests on the docker of the tool being tested.

Definition

//#Patterns: <PATTERN_NAME> : { "<PARAMETER_NAME>": "<PARAMETER_VALUE>" }

var people = {};
//#<PATTERN_LEVEL>: <PATTERN_NAME>
for (var i = 0, person; (person = people[i]); i++) {}

var variable;
function test() {
  //#<PATTERN_LEVEL>: <PATTERN_NAME>
  return (variable = "test");
}

Example:

//#Patterns: boss

var people = {};
//#Warn: boss
for (var i = 0, person; (person = people[i]); i++) {}

var variable;
function test() {
  //#Warn: boss
  return (variable = "test");
}

You can also look for multiple patterns in the same file, just separate them with a comma:

Example:

//#Patterns: big, boss
var people = {};
//#Warn: big
for (var i = 0, person; (person = people[i]); i++) {}

var variable;
function test() {
  //#Warn: boss
  return (variable = "test");
}

Instead of commenting in the line before the error, you can alternatively specify the line of the warning with this syntax:

<LANGUAGE_COMMENT>#Issue: {"severity": "<ERROR_LEVEL>", "line": <LINE_NUMBER_WITH_ISSUE>, "patternId": "PATTERN_ID"}

Example:

//#Patterns: design_tag_todo
//#Issue: {"severity": "Info", "line": 3, "patternId": "design_tag_todo"}

var people = {};
//TODO: remove empty for
for (var i = 0, person; (person = people[i]); i++) {}

var variable;

Multiple test definition

The multiple tests are defined inside the /docs/tests/multiple-tests/ directory of the tool's docker image being tested.

You can have a subdirectory of /docs/tests/multiple-tests/ for every run of the tool.

For example, you can add two subdirectories like these:

• with-config-file
• without-config-file

To check that the tool works with native configuration file (for example .eslintrc.json) and with Codacy configuration.

Each test folder should have a src directory (containining the source files to test and the tool's native configuration (if it exists)), two files named patterns.xml and results.xml with the following structure:

patterns.xml Structure

<?xml version="1.0" encoding="UTF-8"?>

<module name="root">
    <property name="tool-extra-parameter-name" value="tool-extra-parameter-value" />
    <module name="rule-name" />
    <module name="rule-with-parameters">
        <property name="parameter-key" value="parameter-value" />
    </module>
    <!-- To ignore config files from analysis -->
    <module name="BeforeExecutionExclusionFileFilter">
        <!-- value can be a regex matching files to ignore -->
        <property name="fileNamePattern" value="config-file\.xml"/>
    </module>
</module>

results.xml Structure

<?xml version="1.0" encoding="utf-8"?>
<checkstyle version="4.3">
    <file name="file-name.ext"> <!-- severity can be one of info, warning or error -->
        <error source="rule-name" line="20" message="reported message from the tool" severity="info|warning|error" />
    </file>
</checkstyle>

Usage

JsonTests

Checks if the patterns definitions are in the correct format

sbt "runMain codacy.plugins.DockerTest json <DOCKER_NAME>:<DOCKER_VERSION>"

Options:

• codacy.tests.ignore.descriptions - if this variable is defined we do not check if all the patterns have descriptions

PatternTests

Check if all the patterns defined in the test files occur in the specified line

sbt "runMain codacy.plugins.DockerTest pattern <DOCKER_NAME>:<DOCKER_VERSION>"

Options:

• codacy.tests.languages - languages supported by the tool. If this option isn't provided, the languages will be inferred from the test files. Example: -Dcodacy.tests.languages=ruby,java,javascript

Alternatively, you can run a specific test file:

sbt "runMain codacy.plugins.DockerTest pattern <DOCKER_NAME>:<DOCKER_VERSION> no-curly-brackets"

MetricsTests

Check if the metrics defined in the test files match with same complexieties in the specified lines

sbt "runMain codacy.plugins.DockerTest metrics <DOCKER_NAME>:<DOCKER_VERSION>"

MultipleTests

Check if the tool runs with multiple patterns and test files at the same time and configuration file behavior as well

sbt "runMain codacy.plugins.DockerTest multiple <DOCKER_NAME>:<DOCKER_VERSION>"

Options:

• --only by adding this flag, followed by the folder name, you can run a single test of the multiple folder sbt "runMain codacy.plugins.DockerTest multiple <DOCKER_NAME>:<DOCKER_VERSION>" --only <folderName>

Troubleshooting

OSx

Change the java tmp dir to your home so that boot2docker can access the tmp files

-Djava.io.tmpdir=$HOME/tmp
