test-reader

Project designed to identify automated Test Cases scripts and export them to an online target. The Test Cases, along with their types/levels, are identified through regular expressions defined on the yaml configuration file. The purpose is to organize test cases, grouping them by test types, to help managing the tests created as well to serve as input to generate charts and reports of tests distribution.

Currently (version 1.0.x) the tests can be exported only to google spreadsheet.

Settings

Environment Variables

Variable	Description	Required
APP_NAME	The tests will be saved on a sheet of a google spreadsheet. The name of sheet should correspond to APP_NAME, passed on this environment variable	yes
YAML_CONFIG_PATH	This variable contains the path to yaml file, to describe your tests configuration / distribution, the paths you need.	yes
SPREADSHEET_ID	The id of your Google spreadsheet. For more info, check on Google Spreadsheet settings.	yes
CREDENTIALS_PATH	To be able to edit a spreadsheet, you need a credentials json generated on your Google account. For more info, check on Google Spreadsheet settings.	yes

Configuration on Google Spreadsheet

Getting your spreadsheet id

Create a new Spreadsheet in your Google Drive. On URL, your spreadsheet id will be located between https://docs.google.com/spreadsheets/d/ and /edit. See the example below: https://docs.google.com/spreadsheets/d/```1wSAkr0m4D-6YolQycW-aZBV3zvBz0aoxqRCZLDqGeqM```/edit#gid=0

Generating your credentials.json

Go to https://console.cloud.google.com/
Search for Google Sheets API and enable it.
On Google Sheets API, go to Credentials menu.
Click on CREATE CREDENTIALS and select Service Account
Inform any service account name and click on Create.
You will be redirected to Service account permissions, click on Continue.
At this step, go to create key and click at button + Create Key.
Check if JSON option is selected and click on Create. At this step, a json file will be downloaded. This json path should be informed at CREDENTIALS_PATH environment variable.

Associating permission to your spreadsheet

When you generates yout credentials json (usually it's called dark-balancer<random_value>.json), check that there is a field on json named client_email. Copy the value of this field.
Go to your spreadsheet and share it with this email. Note: You will need to give edition permission to this email.
Now you are ready to export your tests. After generating your credentials.json, go to your spreadsheet.

YAML file

The test reader is based on an yaml configuration. This configuration will instruct the script where to find your tests, as well, how to identify it and what is it test type name. This way, you can map the distribution and test types you need, and use it to many languages.

YAML attributes

Attribute	Description	Required
name	Used to map the name of test type. Example: Unit, Component, Integration...	yes
extends	It should have a name of another test configuration, used as parent. With this attribute, all attributes not informed will assume the value from parent. It is valid only for tests in the same path. You can't override path.	no
file_name_regex	Used to define how the test file is named. It should be configured with a regular expression	yes
file_content_contains	Used to select only files that contains a line with an expression. In this case, you have to put the fixed string. (It does not work with regular expression)	no
path	Path where you will find your tests.	yes (if it has no extends)
test_rules / test_description_regex	Test rules will have the filters to identify a test case. The test_description_regex will have the regex to extract your description from a line.	yes (if it has no extends)
test_rules / test_description_strategy	This attribute should have the strategy to get the test description based on test notation. If the description is on the same line of the test notation, you will use SAME_LINE value. If it is on the next line, you should use NEXT_LINE value.	yes (if it has no extends)
test_rules / test_notation	This attribute will inform if the regular expression to identify a new test in the file.	yes (if it has no extends)

Example 1: Simple configuration This example is configured to identify unit tests from Kotlin.

Supposing the following file: ~/projects/my-android-app/app/src/test/java/SumTest.java

class SumTest {
  @Test
  fun `should sum two numbers`() {

  }
}

If you want to map, this test case as Unit, you should use the following yaml:

tests:
  -
    file_name_regex: .*Test\.kt$
    name: Unit
    path: ~/projects/my-android-app/app/src/test/java
    test_rules:
      test_description_regex: "`(.+?)`"
      test_description_strategy: NEXT_LINE
      test_notation: "^@Test+$"

On this example, you will export:

FileName	TestCaseName	TestType
~/projects/my-android-app/app/src/test/java/SumTest.java	should sum two numbers	Unit

Example 2: More complex configuration This example is configured to identify unit and component tests from Kotlin. We are assuming that component tests are in the same directory of unit tests, but the only difference is that component tests has a line with expression @RunWith(AndroidJUnit4::class).

Supposing the following files: ~/projects/my-android-app/app/src/test/java/SumTest.java

class SumTest {
  @Test
  fun `should sum two numbers`() {

  }
}

~/projects/my-android-app/app/src/test/java/SumActivityTest.java

@RunWith(AndroidJUnit4::class)
class SumActivityTest {
  @Test
  fun `should show sum`() {

  }
}

If you want to map, those test cases as Unit and Component, you should use the following yaml:

tests:
  -
    file_name_regex: .*Test\.kt$
    name: Unit
    path: /home/amandaq/projects/my-android-app/app/src/test/java
    test_rules:
      test_description_regex: "`(.+?)`"
      test_description_strategy: NEXT_LINE
      test_notation: "^@Test+$"
  -
    name: Component
    extends: Unit
    file_content_contains: "@RunWith(AndroidJUnit4::class)"

On this example, you will export:

FileName	TestCaseName	TestType
~/projects/my-android-app/app/src/test/java/SumTest.java	should sum two numbers	Unit
~/projects/my-android-app/app/src/test/java/SumActivityTest.java	should show sum	Component

Note in the example above, that we used extends, because the types are in the path. If you have different tests in different paths, you can't use extension.

Samples of configurations to detect test in some frameworks:

Kotlin:

file_name_regex: .*Test\.kt$
test_rules:
  test_description_regex: "`(.+?)`"
  test_description_strategy: NEXT_LINE
  test_notation: "^@Test+$"

Jest:

file_name_regex: .*.test\.js$
test_rules:
   test_description_regex: ".*it\\('(.+?)',"
   test_description_strategy: SAME_LINE
   test_notation: ".*it\\('(.+?)'"

Python:

file_name_regex: .*/test_.*\.py$
test_rules:
   test_description_regex: 'def (.+?)\('
   test_description_strategy: SAME_LINE
   test_notation: 'def (.+?)\('

Cucumber:

file_name_regex: .*/*.feature$
test_rules:
   test_description_regex: '^Scenario( Outline)?:(.+?)$'
   test_description_strategy: SAME_LINE
   test_notation: '^Scenario( Outline)?:(.+?)$' 
   test_exclusion_regex: "^@wip"
   test_exclusion_strategy: "BEFORE_LINE"

JUnit

    file_name_regex: .*Test\.java$
    test_rules:
      test_description_regex: '^public void (.+?)\('
      test_description_strategy: NEXT_LINE
      test_notation: "^@Test+$"
      test_exclusion_regex: "^@Ignore"
      test_exclusion_strategy: "BEFORE_LINE"

Spock

    file_name_regex: '.*/*.groovy$'
    test_rules: 
     test_description_regex: 'def (.+?)\('
     test_description_strategy: SAME_LINE
     test_notation: 'def (.+?)\('
