## ⭐ Features

| Feature            | Description                                                                                                                                          |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------|
| Assertions         | Assertions allow you to quickly check objects for expected values.                                                                                   |
| Fuzzing            | Fuzzing allows you to check functions against sets of generated input parameters.<br/>A couple lines of test code can run thousands of sanity tests. |
| Output Capture     | Capture and validate output written to the terminal.<br/>Perfect for CLI tools.                                                                      |
| Snapshots          | Snapshot objects between test runs, to ensure a consistent behaviour.                                                                                |
| Clean Output       | Clean and colorful output provides you the needed details in an easy-to-understand format.                                                           |
| System Information | Testza prints information about the system on startup.<br/> You can quickly figure out what's wrong, when a user submits an issue.                   |
| Well Documented    | Every function of testza is well documented and contains an example to make usage super easy.                                                        |
| Customizable       | Testza features customizable settings, if you want to change something.                                                                              |
| Test flags         | You can configure testza via flags too!<br/>That makes it super simple to change test runs, or output, without touching code!                        |

## 🚀 Getting Started

See the examples below for a quick introduction!

```go
// --- Some Examples ---

// - Some assertions -
testza.AssertTrue(t, true) // -> Pass
testza.AssertNoError(t, err) // -> Pass
testza.AssertEqual(t, object, object) // -> Pass
// ...

// - Testing console output -
// Test the output of your CLI tool easily!
terminalOutput, _ := testza.CaptureStdout(func(w io.Writer) error {fmt.Println("Hello"); return nil})
testza.AssertEqual(t, terminalOutput, "Hello\n") // -> Pass

// - Fuzzing -
// Testing a function that accepts email addresses as a parameter:

// Testset of many different email addresses
emailAddresses := testza.FuzzStringEmailAddresses()

// Run a test for every string in the test set
testza.FuzzStringRunTests(t, emailAddresses, func(t *testing.T, index int, str string) {
  user, domain, err := internal.ParseEmailAddress(str) // Use your function
  testza.AssertNoError(t, err) // Assert that your function does not return an error
  testza.AssertNotZero(t, user) // Assert that the user is returned
  testza.AssertNotZero(t, domain) // Assert that the domain is returned
})

// And that's just a few examples of what you can do with Testza!
```

Comparing struct values:

person1 := Person{
      Name:   "Marvin Wendt",
      Age:    20,
      Gender: "male",
    }

person2 := Person{
      Name:   "Marvin Wendt",

Example:

init() {
      testza.SetColorsEnabled(false) // Disable colored output
      testza.SetColorsEnabled(true)  // Enable colored output
    }

#### SetDiffContextLines

```go
func SetDiffContextLines(lines int)
```

SetDiffContextLines controls how many lines are shown around a changed diff
line. If set to -1 it will show full diff. You should use this in the init()
method of the package, which contains your tests.

> This setting can also be set by the command line flag
--testza.diff-context-lines.

Example:

init() {
      testza.SetDiffContextLines(-1) // Show all diff lines
      testza.SetDiffContextLines(3)  // Show 3 lines around every changed line
    }

#### SetLineNumbersEnabled

```go
func SetLineNumbersEnabled(enabled bool)
```

SetLineNumbersEnabled controls if line numbers should be printed in
failing tests. You should use this in the init() method of the package,
which contains your tests.

> This setting can also be set by the command line flag
--testza.disable-line-numbers.

Example:

init() {
      testza.SetLineNumbersEnabled(false) // Disable line numbers
      testza.SetLineNumbersEnabled(true)  // Enable line numbers
    }

#### SetRandomSeed

Using the same seed will result in the same random sequences each time and
guarantee a reproducible test run. Use this setting, if you want a 100%
deterministic test. You should use this in the init() method of the package,
which contains your tests.

> This setting can also be set by the command line flag --testza.seed.

Example:

init() {
      testza.SetRandomSeed(1337) // Set the seed to 1337
      testza.SetRandomSeed(time.Now().UnixNano()) // Set the seed back to the current time (default | non-deterministic)
    }

#### SetShowStartupMessage

```go
func SetShowStartupMessage(show bool)
```

SetShowStartupMessage controls if the startup message should be printed.
You should use this in the init() method of the package, which contains your
tests.

> This setting can also be set by the command line flag
--testza.disable-startup-message.

Example:

init() {
      testza.SetShowStartupMessage(false) // Disable the startup message
      testza.SetShowStartupMessage(true)  // Enable the startup message
    }

### Snapshot

#### SnapshotCreate

```go
func SnapshotCreate(name string, snapshotObject any) error
```

SnapshotCreate creates a snapshot of an object, which can be validated
in future test runs. Using this function directly will override
previous snapshots with the same name. You most likely want to use
SnapshotCreateOrValidate.

NOTICE: \r\n will be replaced with \n to make the files consistent between
operating systems.

Example:

testza.SnapshotCreate(t.Name(), objectToBeSnapshotted)

#### SnapshotCreateOrValidate

```go
func SnapshotCreateOrValidate(t testRunner, name string, object any, msg ...any) error
```

SnapshotCreateOrValidate creates a snapshot of an object which can be used
in future test runs. It is good practice to name your snapshots the same
as the test they are created in. You can do that automatically by using
t.Name() as the second parameter, if you are using the inbuilt test system
of Go. If a snapshot already exists, the function will not create a new one,
but validate the exisiting one. To re-create a snapshot, you can delete the
according file in /testdata/snapshots/.

NOTICE: \r\n will be replaced with \n to make the files consistent between
operating systems.

Example:

testza.SnapshotCreateOrValidate(t, t.Name(), object)
    testza.SnapshotCreateOrValidate(t, t.Name(), object, "Optional Message")

#### SnapshotValidate

```go
func SnapshotValidate(t testRunner, name string, actual any, msg ...any) error
```

SnapshotValidate validates an already exisiting snapshot of an object.
You most likely want to use SnapshotCreateOrValidate.

NOTICE: \r\n will be replaced with \n to make the files consistent between
operating systems.

Example:

testza.SnapshotValidate(t, t.Name(), objectToBeValidated)
    testza.SnapshotValidate(t, t.Name(), objectToBeValidated, "Optional message")
