## Introduction
A [Robot Framework](https://robotframework.org/) prerunmodifier for interdependent test cases execution.
Ideally tests are independent, but when tests depend on earlier tests,
[DependencyLibrary](https://github.com/mentalisttraceur/robotframework-dependencylibrary) makes it easy to explicitly declare these dependencies
and have tests that depend on each other do the right thing.
The **DependencyLibrary** provides two Robot Framework keywords: `Depends On Test`
and `Depends On Suite` for defining dependencies between tests and suites.
This **DependencySolver** is a pre-run modifier for Robot Framework, designed to
execute dependent test chains. For instance, if Test C depends on Test B,
and Test B in turn depends on Test A, then all three tests must be run to
ensure Test C can execute successfully. However, if you run Robot Framework with
the command `robot -t 'test C' <path_to_your_test_folder>`, Test C will fail
because this command does not select Tests B and A.
For more details on using the **DependencySolver**, please refer to the section
[Using DependencySolver](##using-dependencysolver).
If you want to run tests parallel with [Pabot](https://pabot.org/), please
refer to section [Using With Pabot](#using-with-pabot).
## Versioning
This library\'s version numbers follow the [SemVer 2.0.0
specification](https://semver.org/spec/v2.0.0.html).
## Installation
If you already have [Python](https://www.python.org/) with [pip](https://pip.pypa.io/en/stable/) installed, you can simply run:
```cmd
pip install robotframework-dependencysolver
```
This will install the latest version of **robotframework-dependencysolver**, along with latest (or sufficiently recent if already installed) versions of **robotframework** and **robotframework-dependencylibrary**.
Additionally, if you are using the **pabot** library, you can ensure that you have a sufficiently recent version of **robotframework-pabot** by running:
```cmd
pip install robotframework-dependencysolver[pabot]
```
After desired installation command, you can verify a successful installation with the following command:
```cmd
depsol --version
```
## How define dependencies with DependencyLibrary
First, include the [DependencyLibrary](https://github.com/mentalisttraceur/robotframework-dependencylibrary) in your tests:
``` robotframework
*** Settings ***
Library DependencyLibrary
```
Typical usage:
``` robotframework
*** Test cases ***
Passing Test
No operation
A Test that Depends on "Passing Test"
Depends On Test Passing Test
Log The rest of the keywords in this test will run as normal.
```
> [!NOTE]
> `DependencySolver` recognizes only `Depends On` keywords defined in `[Setup]`
sections, even though these keywords can technically be used in other parts of
the test. Therefore, it is recommended to specify all dependencies under the
`[Setup]` section, using the built-in keyword `Run Keywords` if needed.
Dependencies, after all, are prerequisites for running a test.
When you need to declare multiple dependencies, just repeat the keyword:
``` robotframework
*** Test cases ***
Another Passing Test
No operation
A Test that Depends on Both "Passing Test" and "Another Passing Test"
[Setup] Run Keywords Depends On Test Passing Test
... AND Depends On Test Another Passing Test
Log The rest of the keywords in this test will run as normal.
```
You can also depend on the statuses of entire test suites:
``` robotframework
*** Test cases ***
A Test that Depends on an Entire Test Suite Passing
[Setup] Depends On Suite Some Test Suite Name
Log The rest of the keywords will run if that whole suite passed.
```
Note that to depend on a suite or a test from another suite, you must
either run Robot Framework with `--listener DependencyLibrary`, or that
suite must also include `DependencyLibrary` in its `*** Settings ***`.
Additionally, you can define `DependencyLibrary` in a common
`some_name.resource` file that is accessible across all suites.
### Skipped Dependencies
If a dependency was skipped, the depending test is also skipped:
``` robotframework
*** Test cases ***
Skipped Test
Skip This test is skipped for some reason.
A Test that Depends on "Skipped Test"
[Setup] Depends On Test Skipped Test
Log The rest of the keywords (including this log) will NOT run!
```
The skip message follows this format:
Dependency not met: test case 'Skipped Test' was skipped.
### Failing Dependencies
If a dependency failed, the depending test is skipped instead of
redundantly failing as well:
``` robotframework
*** Test cases ***
Failing Test
Fail This test failed for some reason.
A Test that Depends on "Failing Test"
[Setup] Depends On Test Failing Test
Log The rest of the keywords (including this log) will NOT run!
```
The skip message follows this format:
Dependency not met: test case 'Failing Test' failed.
### Mistake Warnings
If you depend on a test or suite that does not exist or has not run yet,
``` robotframework
*** Test cases ***
A Test that Depends on "Missing Test"
Depends On Test Missing Test
```
the test will warn and the warning message follows this format:
Dependency not met: test case 'Missing Test' not found.
If you make a test depend on itself or on the suite that contains it,
``` robotframework
*** Test cases ***
Depends on Self
Depends On Test Depends on Self
```
the test will warn and the warning message follows this format:
Dependency not met: test case 'Depends on Self' mid-execution.
## Using DependencySolver
After you have defined the dependencies of each test in the `[Setup]` section by
using `Depends On Test` or `Depends On Suite` keywords, then pre-run modifier
`DependencySolver` checks all `[Setup]` sections and solve dependencies before
running tests. You could use `Depends On Test` or `Depends On Suite` keywords
multiple times and/or together with other setup keywords by using build-in
`Run Keywords` at first.
Write test setup as follows:
```RobotFramework
*** Settings ***
Library DependencyLibrary
*** Test cases ***
Test A
[Setup] Do Test Setup...
[Tags] tagA
Do Something...
Test B
[Setup] Run Keywords Depends On Test name=Test A
... AND Do Test Setup...
[Tags] tagB
Do Something...
Test C
[Setup] Run Keywords Depends On Test name=Test B
... AND Do Test Setup...
[Tags] tagC
Do Something...
```
> [!IMPORTANT]
> `DependencySolver` does not impact the execution order of tests but simply includes the necessary tests and excludes the unnecessary ones. Dependencies can form any tree structure; however, cyclic dependencies (e.g., A -> B and B -> A) will result in an error.
When you have written test dependencies in `[Setup]` sections like above, then
by using `DependencySolver` as `prerunmodifier` you could run whole dependency
chain C -> B -> A by command:
```cmd
robot --prerunmodifier DependencySolver.depsol:-t:"Test C" <other_robot_commands> <path_to_your_test_folder>
```
Additionally, you could use tags also (but only static, not dynamic tags):
```cmd
robot --prerunmodifier DependencySolver.depsol:-i:tagC <other_robot_commands> <path_to_your_test_folder>
```
You can also use shortcut `depsol` directly. This actually calls `robot` with
`--prerunmodifier`, but it is propably more useful when you do not have any
(or at least not many) `<other_robot_commands>`. If you have already navigated
to `<path_to_your_test_folder>`, you does not need to give `--folder` option,
because default is current directory:
```cmd
depsol -t "test C"
```
Or
```cmd
depsol -i "tagC"
```
These commands will have the same effect as the two commands mentioned above.
For more options and help, please run
```cmd
depsol --help
```
`DependencySolver` generates the following two files in the current directory:
- **depsol.log**: An internal log showing the process of traversing and selecting dependencies.
- **depsol.pabot.txt**: A file for use with [Pabot](https://pabot.org/), detailing how the selected tests can be run in parallel while respecting dependencies.
## Using with Pabot
If you want to run tests with Pabot, you need at least version 4.1.0 of the
[robotframework-pabot](https://pypi.org/project/robotframework-pabot/) library.
This version introduces the --pabotprerunmodifier feature, which functions
similarly to prerunmodifier, but it is not passed down to subprocesses.
Instead, it is executed only once in Pabot's main process.
Once the appropriate version is installed, using Pabot is quite
straightforward. The simplest command is:
```cmd
pabot --testlevelsplit --pabotprerunmodifier DependencySolver.depsol:-i:tagC --ordering depsol.pabot.txt <other_commands_to_pabot> <path_to_your_test_folder>
```
However, note that since the example tests A, B, and C depend on each other,
they are grouped together using the `--ordering` file so they are executed in
the same process. The content of the `depsol.pabot.txt` file looks something
like this:
```
{
--test Suite.Test A
--test Suite.Test B #DEPENDS Suite.Test A
--test Suite.Test C #DEPENDS Suite.Test B
}
```
