Maybe

Expect.throws(( ) => Process p = new Process.start(["true"], []),
              (e) => e is ProcessException);

Done for all of them and inlined the three cases in main to make the test
simpler and smaller.

   try {
-    Process p = new Process(["true"], []);
+    Process p = new Process.start(["true"], []);
     Expect.fail("Did not throw exception");
   } catch(var e) {
     Expect.isTrue(e is ProcessException, "Wrong exception type: $e");
   }
 }
 
 void testNonListArguments() {
   try {
-    Process p = new Process("true", "asdf");
+    Process p = new Process.start("true", "asdf");

Ditto.

Done.

     Expect.fail("Did not throw exception");
   } catch(var e) {
     Expect.isTrue(e is ProcessException, "Wrong exception type: $e");
   }
 }
 
 void testNonStringArgument() {
   try {
-    Process p = new Process("true", ["asdf", 1]);
+    Process p = new Process.start("true", ["asdf", 1]);
