Example 7 with TraitExpr

use of org.abs_models.frontend.ast.TraitExpr in project abstools by abstools.

the class TraitTest method resolveTest2.

@Test
public void resolveTest2() {
    // this tests that the given delta is wrong (as we take T union T2 and thus have printLine_2 twice)

    model.applyTraits();

    ModifyClassModifier mm = (ModifyClassModifier) delta.getModuleModifier(0);
    DeltaTraitModifier dml = (DeltaTraitModifier) mm.getModifier(1);
    ModifyMethodModifier mcl = (ModifyMethodModifier) dml.getMethodModifier();
    TraitExpr expr = mcl.getTraitExpr();
    TraitExpr set = expr.resolve(cls.getModuleDecl());
    assertTrue("expected 2, got " + set.getChild(0).getNumChild(), set.getChild(0).getNumChild() == 2);
