In response to

please don't hesitate to notify us about further migration steps you encounter! Source: https://joel-costigliola.github.io/assertj/assertj-swing-migrating.html

Here are the four additional steps I had to perform when upgrading from org.easytesting:fest-swing:1.2 to org.assertj:assertj-swing-junit:3.17.1:

• org.fest.swing.driver.JTableCellValidator.validateCellIndices was renamed to org.assertj.swing.driver.JTableCellPreconditions.checkCellIndicesInBounds
• org.fest.swing.query.ComponentBackgroundQuery.backgroundOf(component) had to be replaced with org.assertj.swing.edt.GuiActionRunner.execute(() -> component.getBackground())
• org.fest.swing.query.ComponentFontQuery.fontOf(component) had to be replaced with org.assertj.swing.edt.GuiActionRunner.execute(() -> component.getFont())
• org.fest.swing.query.ComponentForegroundQuery.foregroundOf(component) had to be replaced with org.assertj.swing.edt.GuiActionRunner.execute(() -> component.getForeground())
