+
+## Properties
+
+Name | Type | Description | Notes
+------------ | ------------- | ------------- | -------------
+**PropTest** | Pointer to **map[string]*os.File** | a property to test map of file | [optional] 
+
+## Methods
+
+### NewMapOfFileTest
+
+`func NewMapOfFileTest() *MapOfFileTest`
+
+NewMapOfFileTest instantiates a new MapOfFileTest object
+This constructor will assign default values to properties that have it defined,
+and makes sure properties required by API are set, but the set of arguments
+will change when the set of required properties is changed
+
+### NewMapOfFileTestWithDefaults
+
+`func NewMapOfFileTestWithDefaults() *MapOfFileTest`
+
+NewMapOfFileTestWithDefaults instantiates a new MapOfFileTest object
+This constructor will only assign default values to properties that have it defined,
+but it doesn't guarantee that properties required by API are set
+
+### GetPropTest
+
+`func (o *MapOfFileTest) GetPropTest() map[string]*os.File`
+
+GetPropTest returns the PropTest field if non-nil, zero value otherwise.
+
+### GetPropTestOk
+
+`func (o *MapOfFileTest) GetPropTestOk() (*map[string]*os.File, bool)`
+
+GetPropTestOk returns a tuple with the PropTest field if it's non-nil, zero value otherwise
+and a boolean to check if the value has been set.
+
+### SetPropTest
+
+`func (o *MapOfFileTest) SetPropTest(v map[string]*os.File)`
+
+SetPropTest sets PropTest field to given value.
+
+### HasPropTest
+
+`func (o *MapOfFileTest) HasPropTest() bool`
+
+HasPropTest returns a boolean if a field has been set.
