Functions ¶
func ApplyTheme ¶
ApplyTheme sets the given theme and waits for it to be applied to the current app.
func AssertCanvasTappableAt ¶
AssertCanvasTappableAt asserts that the canvas is tappable at the given position.
func AssertImageMatches ¶
func AssertImageMatches(t *testing.T, masterFilename string, img image.Image, msgAndArgs ...interface{}) bool
AssertImageMatches asserts that the given image is the same as the one stored in the master file. The master filename is relative to the `testdata` directory which is relative to the test. The test `t` fails if the given image is not equal to the loaded master image. In this case the given image is written into a file in `testdata/failed/<masterFilename>` (relative to the test). This path is also reported, thus the file can be used as new master.
func AssertNotificationSent ¶
AssertNotificationSent allows an app developer to assert that a notification was sent. After the content of f has executed this utility will check that the specified notification was sent.
func AssertRendersToMarkup ¶
func AssertRendersToMarkup(t *testing.T, masterFilename string, c fyne.Canvas, msgAndArgs ...interface{}) bool
AssertRendersToMarkup asserts that the given canvas renders the same markup as the one stored in the master file. The master filename is relative to the `testdata` directory which is relative to the test. The test `t` fails if the rendered markup is not equal to the loaded master markup. In this case the rendered markup is written into a file in `testdata/failed/<masterFilename>` (relative to the test). This path is also reported, thus the file can be used as new master.
Be aware, that the indentation has to use tab characters ('\t') instead of spaces. Every element starts on a new line indented one more than its parent. Closing elements stand on their own line, too, using the same indentation as the opening element. The only exception to this are text elements which do not contain line breaks unless the text includes them.
Since: 2.0
func DoubleTap ¶
func DoubleTap(obj fyne.DoubleTappable)
DoubleTap simulates a double left mouse click on the specified object.
func Drag ¶
func Drag(c fyne.Canvas, pos fyne.Position, deltaX, deltaY float32)
Drag drags at an absolute position on the canvas. deltaX/Y is the dragging distance: <0 for dragging up/left, >0 for dragging down/right.
func FocusPrevious ¶
func FocusPrevious(c fyne.Canvas)
FocusPrevious focuses the previous focusable on the canvas.
func LaidOutObjects ¶
func LaidOutObjects(o fyne.CanvasObject) (objects []fyne.CanvasObject)
LaidOutObjects returns all fyne.CanvasObject starting at the given fyne.CanvasObject which is laid out previously.
func MoveMouse ¶
func MoveMouse(c fyne.Canvas, pos fyne.Position)
MoveMouse simulates a mouse movement to the given position.
func NewApp ¶
func NewApp() fyne.App
NewApp returns a new dummy app used for testing. It loads a test driver which creates a virtual window in memory for testing.
func NewClipboard ¶
func NewClipboard() fyne.Clipboard
NewClipboard returns a single use in-memory clipboard used for testing
func NewDriver ¶
func NewDriver() fyne.Driver
NewDriver sets up and registers a new dummy driver for test purpose
func NewDriverWithPainter ¶
func NewDriverWithPainter(painter SoftwarePainter) fyne.Driver
NewDriverWithPainter creates a new dummy driver that will pass the given painter to all canvases created
func NewWindow ¶
func NewWindow(content fyne.CanvasObject) fyne.Window
NewWindow creates and registers a new window for test purposes
func Scroll ¶
func Scroll(c fyne.Canvas, pos fyne.Position, deltaX, deltaY float32)
Scroll scrolls at an absolute position on the canvas. deltaX/Y is the scrolling distance: <0 for scrolling up/left, >0 for scrolling down/right.
func TapAt ¶
func TapAt(obj fyne.Tappable, pos fyne.Position)
TapAt simulates a left mouse click on the passed object at a specified place within it.
func TapCanvas ¶
func TapCanvas(c fyne.Canvas, pos fyne.Position)
TapCanvas taps at an absolute position on the canvas.
func TapSecondary ¶
func TapSecondary(obj fyne.SecondaryTappable)
TapSecondary simulates a right mouse click on the specified object.
func TapSecondaryAt ¶
func TapSecondaryAt(obj fyne.SecondaryTappable, pos fyne.Position)
TapSecondaryAt simulates a right mouse click on the passed object at a specified place within it.
func Type ¶
func Type(obj fyne.Focusable, chars string)
Type performs a series of key events to simulate typing of a value into the specified object. The focusable object will be focused before typing begins. The chars parameter will be input one rune at a time to the focused object.
func TypeOnCanvas ¶
func TypeOnCanvas(c fyne.Canvas, chars string)
TypeOnCanvas is like the Type function but it passes the key events to the canvas object rather than a focusable widget.
func WidgetRenderer ¶
func WidgetRenderer(wid fyne.Widget) fyne.WidgetRenderer
WidgetRenderer allows test scripts to gain access to the current renderer for a widget. This can be used for verifying correctness of rendered components for a widget in unit tests.
func WithTestTheme ¶
WithTestTheme runs a function with the testTheme temporarily set.
Types ¶
type SoftwarePainter ¶
SoftwarePainter describes a simple type that can render canvases
type WindowlessCanvas ¶
type WindowlessCanvas interface {
fyne.Canvas
Padded() bool
Resize(fyne.Size)
SetPadded(bool)
SetScale(float32)
}
WindowlessCanvas provides functionality for a canvas to operate without a window
func NewCanvas ¶
func NewCanvas() WindowlessCanvas
NewCanvas returns a single use in-memory canvas used for testing
func NewCanvasWithPainter ¶
func NewCanvasWithPainter(painter SoftwarePainter) WindowlessCanvas
NewCanvasWithPainter allows creation of an in-memory canvas with a specific painter. The painter will be used to render in the Capture() call.
